Fall TV 2012: 14 Fresh Faces

Last Big Role: Parker, Sex and the City; Hudson, Something Borrowed
Why They're Buzzy: Glee is famous for its celebrity guest stars, and these two names are some of the biggest the show has seen since Gwyneth Paltrow. Hudson plays Cassandra July, Rachel's (Lea Michele) college dance teacher, who makes meany Maks Chmerkovskiy from Dancing With the Stars look like a teddy bear by comparison. Parker will debut later this season as Isabelle Klempt, a fashionista who becomes a mentor to Kurt (Chris Colfer). For the stylish star — and red carpet fave — the role should fit like a glove. —Erin Strecker

Last TV Role: The British drama Hustle
Why He's Buzzy: At the end of season 3, Kalinda (Archie Panjabi) prepared for the return of her estranged husband, Nick, with a loaded gun. We never got to see his face, but the anticipation of her husband's debut caused a slew of online speculation about who would nab the part. Enter British actor Marc Warren. ''It's been a marriage a bit made in heaven...or hell,'' Good Wife creator Robert King told EW of the pairing. ''We don't know what will be decided by the year.'' But we're excited to find out. —Breia Brissey

Last TV Role: Leigh, Weeds; Vadsaria, Greek
Why They're Buzzy: There will be some new faces in the Hamptons this year. What remains to be seen is whether these two ladies will help or hinder Emily Thorne's (Emily VanCamp) plot for vengeance. Leigh steps into the highly anticipated role of Emily's not-dead-after-all mother, and Vadsaria will play Padma, a finance whiz colleague — and rumored love interest — of pansexual tech guru Nolan (Gabriel Mann). —Emily Rome

Last TV Role: Chuck
Why She's Buzzy: Strahovski leaves the good-hearted Agent Sarah Walker behind to play Hannah McKay, a woman with a dark past who helps Miami Metro Homicide solve an old murder case. We can't wait to see Strahovski tangle with Dexter (Michael C. Hall) on a show that's been giving us nightmares for six years. —Tara Fowler

Last TV Role: Men of a Certain Age
Why He's Buzzy: Romano made his debut in Tuesday's season premiere to largely favorable reviews — despite fans' initial distaste for his character due to reports that he'd possibly come between Sarah (Lauren Graham) and Mark (Jason Ritter). But after one episode, you can't help but root for this jaded photographer. —Sandra Gonzalez

Last TV Role: The Secret Circle
Why She's Buzzy: After playing bad girl Faye Chamberlain on The Secret Circle, Tonkin joins The Vampire Diaries as Tyler Lockwood's (Michael Trevino) mysterious friend Haley. In a role that's been described as wild and sexy, Tonkin is sure to give Caroline (Candice Accola) some competition for the hybrid's affection. But will the hybrid in question be Tyler? Or Klaus (Joseph Morgan)? —Tara Fowler

Last TV Role: The Walking Dead
Why He's Buzzy: This True Blood alum's role is surrounded by a lot of speculation since the Once Upon a Time team is staying tight-lipped on who this ''mysterious new character'' will be. Maybe he'll carry on Hollywood's Year of the Archer trend as Robin Hood? Maybe he'll face off against Hook as a grown-up Peter Pan? Or perhaps we're in store for an original character coming to Storybrooke. —Emily Rome

Last TV Role: Children's Hospital
Why She's Buzzy: Akerman won the key role of Tessa's (Jane Levy) long-lost mother Alex in August following an extensive search. Creator Emily Kapnek told us to expect plenty of chemistry between Akerman and her costars when she makes her debut as the free-spirited singer-songwriter who's never met her daughter. —Tara Fowler

Last TV Role: Samantha Who?
Why He's Buzzy: Watson, who broke out on Seventh Heaven, joins Gossip Girl's final season as Steven Spence, an entrepreneur who will charm Serena van der Woodsen (Blake Lively)...all the way to the altar? A promo for the final season shows a surprise wedding that suddenly has resonance with Lively's off-screen life. Plus, any man who can call the Upper East Side's most famous denizen ''Sabrina'' and go uncorrected must be someone special — or powerful. —Lanford Beard

Last TV Role: Big Love
Why She's Buzzy: The exit of Paget Brewster from the series at the end of last season left a vacancy on the team, but it won't be there for long. Tripplehorn's Alex Blake, a linguistics expert, is introduced in the premiere. —Sandra Gonzalez

Last TV Role: Law & Order: Special Victims Unit
Why She's Buzzy: The Oscar winner has not been known lately for her cuddly characters, so it's safe to say there will be plenty of conflict when she steps in as Doris McGarrett, the mother of sexy cop Steve McGarrett (Alex O'Loughlin). Oh, and did we mention McGarrett thought mommy dearest was dead until last season's shocking finale? Showrunner Peter Lenkov himself admitted that trust will be an issue. —Lanford Beard

Last TV Role: Saturday Night Live
Why She's Buzzy: Following her exit from SNL, Elliott is now set to join dad Chris Elliott on How I Met Your Mother, playing Janeane, the craziest girl the HIMYM gang has ever encountered. The elder Elliott recurs as Lily's father, Mickey Aldrin, though it is said the two will not share any scenes. —Sandra Gonzalez
