Jake Gyllenhaal is filming the remake of Road House at UFC 285.

Ultimate Fighting Championship fans got a sneak peek at Jake Gyllenhaal’s next movie – which doubled as the backdrop for an upcoming remake of 1989’s Road House – at Saturday’s UFC 285 event.

Between actual bouts at Las Vegas’ T-Mobile Arena, a ripped, shirtless Gyllenhaal entered the ring to film scenes in front of a live audience for Amazon Prime Video Feature about an ex-UFC fighter. Former UFC fighter Jay Hieron and doubles champion Conor McGregor – who will also perform at the new “Road House” – also attended the event.

While filming a weigh-in scene, Gyllenhaal flexed his muscles for the audience and got into a physical altercation with Hieron, who plays his rival in the action film. Recordings from the event shows Gyllenhaal staring down and lashing out at Hieron as part of the intense sequence.

“I can’t even believe I trained six weeks for this s— to fight this piece s—,” says Gyllenhaal during the staged weigh-in. “Now just give me the belt. Come on, motherf— let’s go!”

Gyllenhaal and Hieron too in the ring oppositeThey pretended to dodge and hit each other while the director called out hints and the audience went wild. Another clip from the event shows a camera crew following Gyllenhaal as he strutted into the arena in UFC warm-up gear.

Gyllenhaal is no stranger to the ring (square, no Octagon albeit), having played a boxer in the 2015 Antoine Fuqua-directed drama Southpaw.

The upcoming Road House movie, directed by Doug Liman, is based on the 80’s cult classic of the same name and stars Patrick Swayze as a bouncer with a violent past. Daniela Melchior and Billy Magnussen are also part of the cast of the “Road House” revival.
