This is not a casting rumor. It's not speculation.
Kurt Russell is in talks to join the cast of Fast and Furious 7. The film will be directed by James Wan, who is well-known for horror-films, especially the Conjuring and Insidious, and he also has a directing credit on the upcoming sequel Insidious: Chapter II.
Kurt Russel would be joining the returning cast of Paul Walker, Vin Diesel, Dwayne Johnson and of course Jason Statham.
His role is undisclosed at this time. It's not clear whether he will be joining Dominic's crew or teaming up with Ian Shaw, who had a neat little introduction at the end of the credits in Fast and Furious 6.
The film will be set in L.A, which gives Russel the perfect opportunity as one of his films is titled Escape from L.A.
No word yet on whether he will reprise his role as Snake Plissken.
