Shailene Woodley & Ansel Elgort
Siblings in: Divergent
Love interests in: The Fault in Our Stars
We prefer... The Fault in Our Stars. Divergent was really Woodley's showcase, while Fault gives both actors a chance to go toe-to-toe and play on their natural charisma. It's much more than okay.

Emma Thompson & Hugh Grant
Siblings in: Love Actually
Love interests in: Sense & Sensibility
We prefer... Sense & Sensibility. Thompson and Grant have crackling chemistry that got short shrift amid their strong individual performances in Richard Curtis's ensemble dramedy. Jane Austen's sharp story and Ang Lee's nimble direction makes the most of the actors' rapport.

Paul Rudd & Elizabeth Banks
Siblings in: Our Idiot Brother
Love interests in: Wet Hot American Summer and Role Models
We prefer... The David Wain oeuvre. They played love interests so nice, the former State and Stella trouper-turned-director cast them twice. Barbecue kisses have never been more disgusting and sexy at the same time.

Sarah Michelle Gellar & Ryan Phillippe
Siblings in: Cruel Intentions
Love interests in: I Know What You Did Last Summer
We prefer... Cruel Intentions. Yes, Sebastian and Kathryn weren't blood-related, and yes, there was definitely some canoodling going on, so this is a bit of a grey area, but mere manslaughter doesn't hold a candle to the push-and-pull dynamic of these spoiled step-sib schemers.

Will Arnett & Amy Poehler
Siblings in: Blades of Glory
Love interests in: Arrested Development
We prefer... Blades of Glory. Start with their characters' names — Stranz and Fairchild van Waldenberg — and work your way out. Like Gellar and Philippe before them, Arnett and Poehler's sibs had a taint of incest to their crazily costumed figure skating team...and that's exactly what makes for the so-uncomfortable-you-can't-look-away dynamic. I think you'll agree we have not made a huge mistake on this call.

John Gallagher Jr. & Alison Pill
Siblings in: Pieces of April
Love interests in: The Newsroom
We prefer... The Newsroom. Many might argue that Maggie and Jim are pitifully mismatched and too weak-willed to really make their relationship work, but you can't deny that its stop-and-start complexity has been compelling. Plus, any relationship that has a watershed moment on the Sex and the City bus tour deserves our full attention.

Ashley Greene & Kellan Lutz
Siblings in: The Twilight saga
Love interests in: A Warrior's Heart
We prefer... Twilight. Always Twilight. You don't have to be Alice Cullen to have seen this coming.
8 of 11
Bill Hader & Kristen Wiig
Siblings in: The Skeleton Twins
Love interests in: Adventureland
We prefer... Toss-up. We'll take our Hader and Wiig any way we can get 'em.

Jesse Eisenberg & Anne Hathaway
Siblings in: Get Real
Love interests in: Rio
We prefer... Rio. As they say, birds of a feather.... Eisenberg and Hathaway's small-screen stint as siblings was short-lived after Fox decided Get Real would be a one-and-done. Rio, on the other hand, spurned a sequel and gaggle of little Macaw babies. We'll opt for the electric-blue-plumed happy ending, thanks.

Toni Collette & Steve Carrell
Siblings in: Little Miss Sunshine
Love interests in: The Way Way Back
We prefer... Little Miss Sunshine. Relationships are about bringing the other person up, not tearing them down. The philandering Trent in Way Way Back was Carell's second strike against comedies-only typecasting for the actor, but a real bummer for us. His first foray, as Sunshine's suicidal Proust scholar Frank, proved his chops and put a smile on our face.

BONUS! Elizabeth Olsen & Aaron Taylor-Johnson
Siblings in: The Avengers: Age of Ultron
Love interests in: Godzilla
We prefer... Jury's still out. Godzilla was a monster hit, but even a few seconds' glimpse of the mutant twins in the Captain America: The Winter Soldier post-credits tease has us intrigued. Bring it, Ultron!
