Ryan Dunn, a co-star of the Jackass movies, died today when a sports car he was driving left a highway in Philadelphia, Pennsylvania and burst into flames, police said.
Dunn (34) was driving a 2007 Porsche that police found in a wooded area in outer Philadelphia that was "fully engulfed in flames," police in the West Goshen Township said.
An unidentified passenger also died in the crash which occurred early this morning.
The daredevil personality was part of the crew in the top-grossing Jackass movie franchise that specialised in risky pranks and gross-out stunts, lived in nearby West Chester, Pennsylvania.
A police statement said a "preliminary investigation revealed that speed may have been a contributing factor to the accident."
The Ohio-born Dunn posted a photo to his Twitter account shortly before the crash which seemed to show him drinking with friends.
Besides the Jackass franchise, which has grossed more than $330 million worldwide, Dunn also starred in Haggard: The Movie, an indie comedy in which the tattooed, bearded, daredevil played himself.
