Kristen Wiig, Melissa McCarthy and Rose Byrne, Bridesmaids (in theaters)
SNL standout Wiig (second from right) co-wrote and stars in this Judd Apatow-produced comedy as a down-on-her-luck baker enlisted to play maid of honor for her best friend's wedding. Mike & Molly's McCarthy (at left) and Damages' Byrne (third from left) play diametrically opposed bridesmaids, whose warring influences wreak havoc on Wiig's character. Bonus: Mad Men's Jon Hamm steals a few scenes as Wiig's friend with benefits.

Ed Helms, The Hangover Part II (in theaters)
Come fall, Helms' Andy Bernard might be the new Office boss, but in the meantime, it's Stu's turn to get married... if he can make it to the church in one piece. He's got a full set of choppers this time, but is that… a face tattoo?

Kyle Chandler, Super 8 (June 10)
As Friday Night Lights wraps up its critically acclaimed run, Coach Taylor will next be seen in this top-secret project from J.J. Abrams and Steven Spielberg. We know this much: Chandler plays a deputy who tries to prevent all hell from breaking loose when a series of mysterious events takes place in his town in the summer of 1979.

Ian McShane, Pirates of the Caribbean: On Stranger Tides (in theaters)
The man who created two very different portraits of treachery on Deadwood and Kings is now raising the Jolly Roger. He plays the pirate Blackbeard in the third Pirates film, racing against Johnny Depp's Jack Sparrow to locate the mythical Fountain of Youth.

Mila Kunis, Friends with Benefits (July 22)
Before Black Swan, Kunis was known as one of the stars of That '70s Show and the voice of Family Guy's Meg Griffin. Now, she's the Golden Globe-nominated star of a classy Darren Aronofsky thriller. So this summer, she has cashed in on that clout to star in… a bawdy sexy comedy with Justin Timberlake. Oops.

Steve Carell, Crazy, Stupid, Love (July 29)
Now that Carell has left The Office in his rear view, he is officially a full-time movie star. First up: He plays a recent divorcé who seeks help from a scheming playboy (Ryan Gosling) to reclaim his manhood. Julianne Moore, Emma Stone and Marisa Tomei co-star.

Blake Lively, Green Lantern (June 17)
While Serena van der Woodsen, the character Lively plays on Gossip Girl, is getting her feet wet as a Hollywood D-girl this summer on director David O. Russell's Fitzgerald project, the actress will play Carol Ferris, the A-list love interest of Ryan Reynolds' Hal Jordan in the big-screen adaptation of the classic DC comic book.
8 of 15 Sony Pictures
Neil Patrick Harris and Sofia Vergara, The Smurfs (July 29)
Harris (How I Met Your Mother) and Vergara (Modern Family) co-star in this summer's 3-D Smurfs movie. She plays a French cosmetics-company executive and he plays her employee. Glee's Jayma Mays is Harris' wife. There are also tiny animated blue people in the movie, we hear.

January Jones, X-Men: First Class (June 3)
Thanks to protracted contracted negotiations, it's going to be at least another six months or so before we see Jones back at work playing desperate housewife Betty Draper on Mad Men, but Jan fans can bask in her powers sooner than that when she plays the sexy, smart, translucent Emma Frost in this summer's X-Men prequel.
10 of 15 Columbia Pictures
Jason Segel, Bad Teacher (June 24)
While subpar substitute Cameron Diaz attempts to land rich-guy Justin Timberlake, Segel plays Russell, the nice-guy gym teacher who pines for her from the sidelines. (You just know that How I Met Your Mother's Marshall is really good at dodgeball.)
11 of 15 John P. Johnson/Warner Bros. Pictures
Jason Sudeikis, Horrible Bosses (July 8)
SNL all-star Sudeikis, Jason Bateman and Charlie Day (from It's Always Sunny in Philadelphia, incidentally) play a trio of friends who conspire to off their bosses: a shifty salesman (Kevin Spacey), a lecherous dentist (Jennifer Aniston, hilariously!) and a balding, politically incorrect menace played by — who else? — Colin Farrell.

Olivia Wilde, Cowboys & Aliens (July 29)
House fans, remember how Thirteen disappeared for most of last season? Well, this is why. Wilde was shooting this Western/sci-fi mashup with Harrison Ford and Daniel Craig. In it, she plays Ella, a mysterious character who helps Craig fight the little green men.
13 of 15 Brian Andrew Mendoza/Lionsgate
Jason Momoa and Ron Perlman, Conan the Barbarian (August 19)
By the time Momoa arrived on the Game of Thrones set, he'd had plenty of practice playing a primitive warrior in the lead role of the remake of the film that made Arnold Schwarzenegger a household name. Perlman (Sons of Anarchy) co-stars as Conan's doomed dad.
14 of 15 Columbia Pictures
Danny McBride, 30 Minutes or Less (August 12)
McBride took a detour into series TV for HBO's Eastbound and Down, but this summer he's back on the big screen as a criminal who forces two regular guys (Jesse Eisenberg and Aziz Ansari) to rob a bank.

Bryan Cranston, Larry Crowne (July 1)
As morally compromised Walter White on Breaking Bad, Cranston evokes an odd kind of sympathy. No such luck in this role, where he plays Julia Roberts' blogger husband who has a penchant for porn. No wonder she runs into Tom Hanks' arms.
