Vin Diesel made exactly zero movies last year, and this year's entry -Babylon A.D.- came out and tanked.
So what's your next career move if you're the 41 year-old action star? You do a Sly Stallone. You return to the series that put you on the action-star map.
This June, Vin Diesel returns in his second Fast and Furious film - the fourth in the series (he skipped two and three). Meanwhile, he's also suiting up for XXX: The Return of Xander Cage for the third entry in that series. Ice Cube played the part in XXX: State of the Union which didn't do the kind of business the first film did.
Not that Diesel-and-sequels are a guarantee of success. He did make the sequel to his smash Pitch Black, but The Chronicles of Riddick failed to connect with audiences.
