Rupert Alexander Grint was born on August 24, 1988, in Hertfordshire, England, UK. Although only acting in one school play before being cast in the popular wizard series "Harry Potter," Rupert has already proved himself one of the most recognized actors on the big screen. When he heard that there were going to be auditions for Harry Potter and the Sorcerer's Stone, he decided to try out for it.

Unlike the other children who were auditioning, Rupert came in with hip-hop lyrics that promoted Ronald Wasley, the character for which he was auditioning, and was chosen soon afterward. Harry Potter and the Sorcerer's Stone was a big hit, as was the follow-up, Harry Potter and the Chamber of Secrets, and he has already filmed episode three, Harry Potter and the Prisoner of Azkaban, which was released on Friday, June 4, 2004. More recently, he finished filming the fourth movie, Harry Potter and the Goblet of Fire.
Has one brother and three sisters. On his audition tape for Harry Potter, he performed hip-hop lyrics that he wrote to promote himself for the role of Ron Weasley. Loving the Harry Potter series, Rupert Grint found out that there were auditions for the feature film, so he got the part although he had previously only acted in one school play.
