Action man Dwayne Johnson has a Facebook fan to thank for his role as a federal marshall in the new Fast & The Furious sequel - producer/star Vin Diesel originally had Tommy Lee Jones in his mind for the part.
Diesel was scouting for ideas from fans online just before filming on Fast 5 started and one suggested Johnson should play an out-of-character bad guy.
The Xxx star thought it was a great idea and started calling the former wrestler's agents.
Johnson says, "There's a lot of people taking credit for me being in the movie... but I know, to Vin, that was, like, a defining moment for him, because he had read it (script) and, at that time, a director was flying in to meet with him... So give a lot of credit to that fan."
