To me, one of the most exciting parts of watching films is see who has the potential to be a star in Hollywood in the years to come. This thread is for who you consider to be future stars in the business.
Actors
Nicholas Hoult
I first saw him in About A Boy in which he was very impressive. In the past two years he appeared in X-Men: First Class offering sympathy to the character of Beast, Warm Bodies a comedy where he plays a zombie and now is the feature actor in Jack The Giant Slayer. He's gotten his face out there and now he's getting starring roles and I think he'll be a big star for years to come.
Kodi-Smit McPhee
Though his exposure is minimal up to now, he impressed with me equally with his roles in The Road opposite Viggo Mortensen and in Let Me In opposite Chloe-Grace Moretz, though he has five projects in the near future. Eagerly waiting to see what else he can do.
Tom Holland
Despite his only project thus far being The Impossible, his performance carried a majority of the movie and the scenes he carried were the most moving of the film, outshining even screen vets Naomi Watts and Ewan McGregor.
Jared Gilman
Cast as the lead in Wes Anderson's Moonrise Kingdom he had no name or resume to himself and it's amazing how well he did. He did an amazing feat by playing an adult as a child.
Actresses
Jennifer Lawrence
It only took Jennifer Lawrence a couple of years to be nominated for an oscar, a couple more to win. She not only is a beautiful actresses but can play diverse roles, from indie films to blockbusters and she does it all seemingly without even trying. I see a future Meryl Streep here.
Chloe Grace Moretz
The first time I saw her was in 500 Days of Summer, giving relationship advice to her twice older brother and she had so much confidence. In Hugo she showed the grace and poise of a classical actress. In Kick-Ass she shocked us. In Let Me In she both frightened and intrigued us. With Kick-Ass 2 coming down the pipe and playing Carrie opposite Julianne Moore, the sky is the limit. At her young age she has already proven to be a 5 tool actress which is extremely rare.
Jessica Chastain
No one has exploded onto the scene has Jessica Chastain has the past two years, with a powerhouse performance in Tree of Life, followed by her two oscar nominated roles in The Help and Zero Dark Thirty. How successful she will be a decade from now is up to her and her choices.
Mia Wasikowska
If you haven't seen her in In Treatment, do it now, she's amazing. On the big screen she landed the title role in Alice and Wonderland, starred opposite Annette Benning, Julianne Moore and Mark Ruffalo in the great The Kids Are All Right and showed her talents as Jane Eyre opposite Michael Fassbender. With the combination of her appearance and confidence in her abilities, she has an uncanny ability to show both strength and vulnerability simultaneously.
Alison Pill
Here is another great young actress whose talents were noticed on the show In Treatment. On the big screen she hasn't had the starring role success of those else on my list she knocks whatever she can get out of the park, just see her as Zelda Fitzgerald in Midnight In Paris to see what I mean. Currently she is a central character in The Newsroom with Jeff Daniels.
Kara Hayward
Much like Jared Gilman her first role was in Wes Anderson's Moonrise Kingdom, in which much of her performance was based on her seeming inability to express any emotions but you know she can feel them.
