Rebecca Hall is set to have a pretty great birthday. The British actress turns 31 on May 3, the same day her biggest movie ever, a little something called "Iron Man 3," arrives in U.S. theaters. The blockbuster has already earned almost $200 million worldwide, giving Hall her biggest audience ever.
Hall, fortunately, isn't the only actor poised to reap the rewards of a breakout summer film. From "Star Trek" villain Benedict Cumberbatch to festival favorite Michael B. Jordan to the perpetually awkward Aubrey Plaza, the next Channing Tatums and Rebel Wilsons will be all over theaters this summer.
Ahead, HuffPost Entertainment presents 17 actors with the biggest chance of breaking out between now and Labor Day.
