Mastodon star Brent Hinds has been cast as tragic Jackass stuntman Ryan Dunn in a new movie.

The biopic, I Needed Time to Stay Useless, is being developed by the Tv and film star's best friend Bam Margera, and he reveals Hinds has been astonishing in his feature film debut.

Dunn, who bore a notable resemblance to the guitarist, lost his life in a 2011 car crash in Pennsylvania, aged 34.
