12. James and Oliver Phelps
Artistic credibility: James and Oliver have worked sparsely since their time as the Weasley twins but have joint parts in the upcoming film Own Worst Enemy.
Commercial viability: The twins' ties to the world of Harry Potter are still strong, and they are featured in The Wizarding World of Harry Potter.
Extracurricular achievements: Not much. They've been really working their Potter connections.
Final evaluation: They might forever stay Weasley. Nice work if you can get it.

11. Evanna Lynch
Artistic credibility: The actress who played Luna Lovegood appeared in the well-received but little seen indie G.B.F. She has a part in Dynamite: A Cautionary Tale, which also stars Carol Kane, and the Irish film My Name Is Emily.
Commercial viability: Not much.
Extracurricular achievements: She's been vowing to teach J.K. Rowling how to use emoji.
Final evaluation: Stateside, Lynch hasn't been quite as elusive as the Crumple-Horned Snorkack Snorkack—but close.

10. Matthew Lewis
Artistic credibility: Neville Longbottom surprised everyone by getting really really attractive; however, he has kept his talents mostly in Britain, with roles in small films, two BBC series, and on stage. He made his West End debut in 2012. He is reportedly signed on to a movie about the Bronte siblings.
Commercial viability: He's basically a meme, so that counts for something, right?
Extracurricular achievements: That shirtless ice bucket challenge video probably shouldn't be taken for granted.
Final evaluation: Clearly there's an audience for Lewis.

9. Bonnie Wright
Artistic credibility: The ginger formerly known as Ginny Weasley has appeared in a variety of films that have received very little attention (at least in the United States), though she recently signed on to a thriller with Nikki Reed. She also is directing, according to a recent profile in the London Evening Standard.
Commercial viability: Hard to say.
Extracurricular achievements: Wright has a history of humanitarian work, traveling to Senegal with Oxfam and has blogged for the Huffington Post about her Global Poverty Project campaign the Live Below the Line challenge. Her personal life has also interested tabloids following her engagement to Potter costar Jamie Campbell Bower, which ended in 2012.
Final evaluation: Wright may not have many film credits of note, but her celebrity is still relatively strong.

8. Luke Youngblood
Artistic credibility: Youngblood made less of an impression as Lee Jordan in the first two Potter films than he did as Magnitude on Community. Everyone together now: ''Pop! Pop!'' He also has a part on ABC's midseason show Galavant.
Commercial viability: Hard to quantify now but at least he has a catchphrase and an oral history around his character.
Extracurricular achievements: It's not really an extracurricular, but he gave the motion-captured performance as Scooby-Doo in Scooby-Doo! Curse of the Lake Monster for Cartoon Network.
Final evaluation: Pop! Pop!

7. Tom Felton
Artistic credibility: Felton has had a solid career following his turn as sniveling villain Draco—often playing, well, sniveling villains. He got to deliver the ''damn dirty ape'' line in Rise of the Planet of the Apes and has done some supporting roles in period pieces including In Secret and Belle. He also played a bad guy in TNT's Murder in the First.
Commercial viability: Rise of the Planet of the Apes defied skepticism for a strong box office, and Vulture deemed Belle the ''secret hit'' of summer 2014, but Felton certainly wasn't the main draw in either case.
Extracurricular achievements: He sings recreationally and dates a model. Not too shabby, not too outstanding considering his line of work.
Final evaluation: Felton has carved out a niche for himself and gets roles that keep the Dark Lord's wrath at bay.
7 of 12
6. Rupert Grint
Artistic credibility: Poor Ron Weasley hasn't had much runaway post-Potter success, though he's on the upswing with a role in Broadway's most sought after ticket It's Only a Play, adding to his theater resume after his stage debut in London in 2013. On screen, he had an actually-pretty-good pilot called Super Clyde that didn't make it to series and a couple of roles in forgettable indies like Charlie Countryman and CBGB.
Commercial viability: It's Only a Play has become ''one of five Broadway hits to exceed the maximum gross potential of its venue,'' EW reported, but Grint is certainly not the only or biggest star in the cast.
Extracurricular achievements: He had a song on the soundtrack for an animated film, on which he also did voice work, and starred in a video for Ed Sheeran's ''Lego House.'' He also owns an ice cream truck.
Final evaluation: Grint's post-Potter career has been positively Weasley-ish, fine, but sort of under-achieving.

5. Alfie Enoch
Artistic credibility: Aside from his Harry Potter role as Dean Thomas, Enoch didn't have much to his film and TV résumé before 2014. (He was in an episode of Sherlock! He's done classical theater in the U.K.!) And then came How to Get Away with Murder.
Commercial viability: HTGAWM had a great ratings debut and has a full season order.
Extracurricular achievements: He studied at Oxford and has a charming story about streaking through the Harry Potter set.
Final evaluation: HTGAWM has been hailed not just as great entertainment but a groundbreaking show. Whether Enoch will be the biggest breakout of the cast remains to be seen (costar Jack Falahee is giving him a serious run for his money), but a well-received leading role on a network show is a major building block for a solid career.

4. Domhnall Gleeson
Artistic credibility: As Bill Weasley, Gleeson didn't have much to do in the Harry Potter series, yet he's on the road to becoming one of the most successful Hogwarts alumni. Gleeson broke out in last year's Richard Curtis dramedy About Time and was the audience's guide in the Michael Fassbender in a papier-mâché head movie Frank. He impressed Angelina Jolie, who cast him in a supporting role for awards-bait biopic Unbroken, and he's got the freaky-seeming Ex Machina slated for April. But the biggest get for Gleeson is his casting in J.J. Abrams' upcoming Star Wars movie. That's a game-changer that catapults him to the top five on this list.
Commercial viability: Certainly no one is rushing to see a Domhnall Gleeson movie, but let's see what happens after Star Wars.
Extracurricular achievements: You can watch him actually play in the Frank band on Colbert.
Final evaluation: Of the actors on this list, Gleeson was among the least defined by his work in Harry Potter, which allowed him to define himself elsewhere and turn into a reliable Hollywood player.

3. Daniel Radcliffe
Artistic credibility: The man who played Harry himself lands in third place, which is not a dig at anything Radcliffe has done post-Potter. In fact, he's made excellent choices. Even before Potter was done, he bravely appeared in Equus in London and on Broadway, a role that mostly got him attention for being naked but also proved he could act in 8 performances a week. He has since tackled two completely different roles on the boards of Broadway and the West End, learning to be a song and dance man in How to Succeed in Business Without Really Trying and playing the titular character in The Cripple of Inishmaan. His film roles have been equally varied, playing Allen Ginsberg in Kill Your Darlings, trying his hand at romantic comedy in What If, and talking to snakes (again!) in the horror-comedy Horns. On TV, Radcliffe has taken on the historical and surreal A Young Doctor's Notebook with Jon Hamm.
Commercial viability: Radcliffe is more commercially attractive on Broadway than he has been in non-Potter films, with What If underwhelming at the box office this summer despite lovely reviews.
Extracurricular achievements: Radcliffe has clearly been pushing himself acting-wise and it's paying off in respect. More importantly, though, he's a media charmer. Witness his ''Alphabet Aerobics'' rap.
Final evaluation: Radcliffe has proved he can do just about anything acting-wise. Now it's time to make that consistently bankable.

2. Robert Pattinson
Artistic credibility: Cedric Diggory has been in a little-known film series following his time in Harry's world. We're kidding. He was in Twilight. And even though Twilight may have made him incredibly famous (not to mention the butt of many jokes), he upped his indie cred in recent years thanks to collaborations with David Cronenberg on the festival favorite Maps to the Stars. He also has projects with Harmony Korine, Olivier Assayas, Werner Herzog, and Anton Corbijn in the works.
Commercial viability: Twilight was obviously a huge hit, but his more off-beat work hasn't been able to draw in audiences based on his star power alone. His recent The Rover was unsuccessful in attempts to lure an expanded audience. His film career isn't the only thing helping him along, though. He does, after all, have those cheekbones and was named the face of Dior Homme.
Extracurricular achievements: Sadly, R-Pattz's longterm relationship with his Twilight costar dominated much of the conversation about his career—even though the only confirmation of their off-screen relationship came in the midst of their break. Now he is linked to musician FKA twigs.
Final evaluation: Pattinson has strayed away from romantic roles that recall Twilight (i.e. Remember Me and Water for Elephants) into grittier fare that rebrands him as an actor not exclusively known for his sparkle.

1. Emma Watson
Artistic credibility: As an actress, Watson has made a range of smart (and mature) choices after she ended her time as Hermione, including a well-received YA movie in which she tested out her American accent (The Perks of Being a Wallflower), a biblical epic (Noah), a self skewering cameo (This Is the End), and an against-type role in a Sofia Coppola flick (The Bling Ring). The last film on that list yielded her greatest line delivery to date—''I wanna rob.'' She's likely signed up for Whiplash director Damien Chazelle's upcoming musical with Miles Teller and is planning a reunion with Perks director Stephen Chbosky.
Commercial viability: The Bling Ring opened to Sofia Coppola's best per-theater average, and Noah won its opening weekend. Watson also has fashion world clout, sitting in the front row at Dior Couture's Paris show this year with Jennifer Lawrence, having done campaigns for Lancôme and Burberry (while she was still in her Potter years).
Extracurricular achievements: Where Watson outmatches her Hogwarts cohorts is in her extracurricular activities and her achievements for muggles the world across. Not only did she graduate from Brown, she became a U.N. Women Goodwill Ambassador. Perhaps her most notable work to date came in the form of a galvanizing speech about feminism that launched the HeForShe campaign.
Final evaluation: Watson wins this ranking for being an all-around overachiever. Typical Hermione.
