Rupert Grint
Age: 23
What He's Done: As the loyal, charming and increasingly buff Ron Weasley, Grint helped lead the 'Harry Potter' franchise to somewhere near a ka-billion dollar worldwide gross. The British native also appeared in 'Wild Target' with Bill Nighy and Emily Blunt.
What's Next: The historical drama 'Comrade,' about two pilots (English and German) who shoot each other down during the war and wind up in the same secluded cabin in the Norwegian woods. He's also attached to 'Eddie the Eagle,' about England's first Olympic ski jumper.
Did you know? Grint showed up to support 'Harry Potter' co-star Tom Felton at the premiere of 'Rise of the Planet of the Apes' wearing a homemade 'I [Heart] Tom Felton' T-shirt.
