Vin Diesel risked his home to finance new Riddick film

Hollywood tough guy Vin Diesel put his house at risk to complete production on his new film Riddick.

The star has played anti-hero Richard B. Riddick in two movies - 2000's Pitch Black and 2004's The Chronicles of Riddick - and now he's reprising his role in the franchise's latest movie, due out next month (Sep13).

However, Diesel has faced a nine-year battle to make the movie, which didn't have the financial backing of its predecessors, forcing the actor to use his own money to complete the project.

He tells The Hollywood Reporter, "I had to leverage my house. If we didn't finish the film, I would be homeless."

But Diesel insists the risk makes the him even more proud of the finished product: "It's a strange and unique sense of gratification, and it's not like any film I've done in the last 10 years."
