Vin Diesel goofs off with Jason Momoa in a new video from the set of Fast 10.

F9: The Fast Saga was the biggest entry in the Fast & Furious franchise to date, introducing several new characters and even sending a car into space for the first time.

Not long after F9 was released, it was confirmed that Dominic Toretto (Diesel) and the rest of the gang would return in two additional installments, which would act as a conclusion to The Fast Saga.

The plot of Fast 10 remains unknown, but Diesel revealed the official title of the film, Fast X, back in April.

In addition to regular cast members like Jordana Brewster, Michelle Rodriguez, Ludacris, and Tyrese Gibson, Fast 10 will introduce several new characters, including a villain by Momoa and a currently unknown character played by Brie Larson.

Although now just over a month into filming Fast 10, the movie has already been plagued by a ballooning budget and reports of issues behind-the-scenes, many of which came to light after director Justin Lin's sudden announcement that he was departing the film.

In a new post on Instagram, however, Diesel shows that he's clearly still having a great time making Fast 10, with the actor sharing a video of him goofing off with Momoa on the set of a major action sequence.

The video features a shirtless Momoa lying on the hood of a purple muscle car, joking that he's "trying to be in the new Whitesnake video."
