DIESEL PUTS PEDAL TO THE METAL!

Under pressure by studio & fans to speed it up - or he's done!

- 

AGING action star Vin Diesel has come under fire from overzealous fans after endless delays on Fast & Furious 11, and sources reveal he's scrambling to save the flick before the franchise crashes and burns!

"It's been a long, tortured journey to get this movie up and running," spills an industry insider. "Even though there's been some preproduction and pre-shooting, the full ensemble isn't going to assemble until later this spring after many months of delays and a lot of uncertainty about budget and location."

Meanwhile, the whole franchise seems to already be running on fumes!
