Furious 7, the movie that is effectively a memorial to actor Paul Walker, will win best picture at next year's Oscars, according to the film's star and producer Vin Diesel.

Diesel confidently told Variety the latest release in The Fast and the Furious franchise would be "the biggest movie in history" and was a dead cert for the top award in 2016.

"This will win best picture," he said. "There is nothing that will ever come close to the power of this thing."
