A new picture (full size below) shows both Vin Diesel and Jason Statham alongside each other in Fast & Furious 7 (2015). Considering that both are smiling at each other it seems to be a candid or simple behind the scenes shot.
Exercising my memory here a little bit, this scene is from a car lot roof in Los Angeles. Some have speculated it’s from Dubai, but I’m kinda sure it isn’t. The sand-coloured background is a wall. However what’s interesting is that the L.A. scene was shot at night and it almost looks like they’ve CGI’ed the daylight in?
In the scene in question two cars, speculated to be Diesel’s and Statham’s, are rammed into each other headlong.
In the movie Statham is out to avenge the death of his brother. Rumour has it that Tony Jaa is another pissed sibling, the brother of Johnny Tran.
