Grint playing the part of Ron Weasley.A self-proclaimed fan of the Harry Potter book series, young Grint was interested in getting a role in the film. For his audition, he sent a video he made of himself, in which he dressed as his drama teacher, while rapping about how much he wanted the part and won the casting selection with it.
After completing the first Potter film, Harry Potter and the Philosopher's Stone (released in the United States as Harry Potter and the Sorcerer's Stone), he appeared as Alan A. Allen in the British comedy film Thunderpants (2002).

On 9 July 2007, Grint and fellow cast-mates Daniel Radcliffe and Emma Watson left imprints of their hands, feet and wands in front of Grauman's Chinese Theater in Hollywood.
While directing Prisoner of Azkaban, Alfonso Cuarón is reported to have gained the strong impression that Grint is "the likely future star out of the Hogwarts trio".

When not working, he enjoys learning to ride the unicycle, drawing/sketching, and playing golf.
