Rupert Grint made his big-screen debut in 2001's box-office smash Harry Potter and the Sorcerer's Stone, bringing to life Ronald Weasley, friend to the famous protagonist Harry Potter of J.K. Rowling's children's novel. Born in England in 1988, Grint had only performed in plays for school and local theater in Europe before making the giant leap into Hollywood with Harry Potter. He scored a role in the family comedy Thunderpants soon afterward, but was kept busy for the next several years as audiences saw him grow up alongside co-stars Daniel Radcliffe and Emma Watson while appearing in the ongoing Harry Potter sequels. He emerged in 2006 with a starring role in the well-received comedy drama Driving Lessons, alongside Hollywood heavyweights Julie Walters and Laura Linney. ~ Rovi
