From Bradley Cooper (A-Team) to Milla Jovovich (Resident Evil: Afterlife), we bring you this summer’s 20 stars to watch.

By Elisa Osegueda

We begin the roundup with Bradley Cooper, whose popular films, including The Hangover and this summer’s 80’s TV remake The A-Team, continue to place him center stage. Even though he’s dating Renee Zellweger, we won’t hate…sigh, Cooper is currently filming Hangover 2 and The Dark Fields with Robert De Niro.

Tom Cruise

This “mission impossible” lead actor never fails—Tom Cruise, star of June’s Knight and Day, will be hitting the big screen next year with Mission Impossible IV. Cruise is also working on a project with Denzel Washington.

Robert Pattinson

2010 marks the third consecutive year that vampires and werewolves continue to be a sensation. Case in point: Robert Pattinson, Bella’s one true love in The Twilight Saga: Eclipse, but …

Taylor Lautner

Pattinson isn’t the only one vying for Bella’s love…Taylor Lautner co-starred in Eclipse as the teenage wolf ready to sacrifice anything to win over Bella’s heart. Watch out for Lautner as the young Hollywood actor dives into his next film project—Stretch Armstrong.

Helen Mirren

There’s a classic beauty in Helen Mirren that never fades. She recently starred in Love Ranch alongside Joe Pesci. They play a married couple who own the first brothel in Nevada, but this sexy lady cheats on her husband with a young hot boxer! Scandalous! She’ll be costarring with Bruce Willis and Morgan Freeman in RED.

Adrien Brody

Adrien Brody gained instant sex appeal in '03 when he locked lips with Halle Berry while accepting his Oscar for Best Actor. Don’t be fooled—underneath the hipster clothes Brody rocks those abs, especially in July's sci-fi horror redo Predators.

...told you so.

Alice Braga

Alice Braga might be slightly overlooked by some, but this Brazilian hottie has co-starred with A-lister’s—Adrien Brody in Predators and Jude Law in Repo Men. She’ll also be working alongside Anthony Hopkins in The Rite, due out next year.

Leonardo DiCaprio

Leonardo DiCaprio. Does he need an introduction? The Inception star had us marveling over his performance as Cobb, so, of course, we can’t wait to see him in his next role as J. Edgar Hoover in Hoover.

Marion Cotillard

The decadent Marion Cotillard continues to impress audiences…and it was only a matter a time before she caught the eye of director Woody Allen. The French actress will be working with Allen in Midnight in Paris.

Angelina Jolie

This Hollywood star can easily make any man drool, throws some mean punches, and she’s dating one of the hottest men in Hollywood. Her spy-thriller Salt is out in theaters, but expect an even hotter performance from Jolie next year as she co-stars with Johnny Depp in The Tourist.

Zac Efron

This Charlie St. Cloud star is one of the most desirable teen heartthrobs to date. So kudos to Zac Efron, because the kid can act and sing, all while looking charmingly cute.

Michael Cera

Michael Cera = Adorable. Though Scott Pilgrim vs. The World didn't wow the box office, the movie earned much critical acclaim and for good reason. Now rumor has it that Cera might be starring in Gilligan’s Island the movie.

Julia Roberts

Julia Roberts, the pretty woman of our generation, returned to the big screen with Eat, Pray, Love. Roberts plays a recently divorced woman who risks it all by going on a global trek in hopes of finding herself. The Oscar winner will soon be seen with buddy Tom Hanks in Larry Crowne.

Drew Barrymore

This beloved child star has blossomed through out the years, and there’s no way our round up would be complete without Drew Barrymore. The director, producer, Golden Globe winner and Covergirl model stars alongside Justin Long in Going the Distance.

George Clooney

George Clooney. We know, we know, he’s on every hot list, but you’ve got to admit that the man looks good! And he’s looking pretty fine in the trailers released for The American, a drama thriller set in Italy in which Clooney plays an assassin in hiding. It hits theaters in September, so make sure you pencil the release date in your calendars.

Jessica Alba

Robert Rodriguez's Machete has an all-star cast from Danny Trejo to Robert De Niro. And let’s not forget Jessica Alba and Michelle Rodriguez, two hot Latinas whose talents are cementing their names in Hollywood. Alba plays a U.S. Immigration and Customs Enforcement Agent.

Michelle Rodriguez

Michelle Rodriguez is known for her tough, sucker-punching roles, and she doesn’t miss a beat in Machete as Luz, a saucy taco slinger.

Milla Jovovich

The Resident Evil: Afterlife star Milla Jovovich is annihilating every beast she comes across in the fourth installment of the Resident Evil franchise. The beauty will be co-starring later this year in Stone with Edward Norton and Robert De Niro.

Ben Affleck

Ben Affleck is ready to remind everyone why he’s an Oscar winner. Blake Lively, John Hamm and Jeremy Renner are a few stars joining the stud in The Town. Affleck directed and co-wrote the screenplay with Peter Craig.

Shia LaBeouf

We end the roundup with Shia LaBeouf, the young actor who is maturing gracefully on screen with stronger and edgier roles. His latest film Wall Street: Money Never Sleeps is directed by Oliver Stone and set for release in September. Shia co-stars with Carey Mulligan and Michael Douglas. He’s currently filming Transformers 3 with Victoria Secret model Rosie Huntington-Whiteley.
