Road House: UFC Cuts Jake Gyllenhaal Epic Fight Promo Ahead of McGregor Faceoff

Gyllenhaal's Dalton is seen in the promo training at the UFC Performance Institute and more of the star's Hollywood highlights are caught on camera. 

"Elwood Dalton, this guy's very confident and of the best fighters we have ever seen in the UFC," UFC play-by-play expert Jon Anik read off the script. 

Hieron's "Jax 'Jetway' Harris" also gets some shine as 'the most dominant champion in the game', according to Joe Rogan's commentary in the promo. 

Spoiler alert! If you somehow missed the footage of 'Dalton vs. Harris' spreading like wildfire live at UFC 285, here it is:

Gyllenhaal mounted a climactic comeback to knock out Hieron with a flying knee in the opening round of the choreographed fight. But, the action didn't stop there as Gyllenhaal did his best impression of Jorge Masvidal and swung for more 'super necessary' shots on his already decimated opponent.

Jay Hieron relives filming the scene with Gyllenhaal in front of 19,000+ fans in the T-Mobile Arena in Las Vegas, Nevada.

"When you’re dealing with a live event, a live crowd, we were using the UFC’s camera angles – we usually have a camera set up in a way to help sell the choreography – no, no, we’re dealing with a live crowd, where if it looks terrible, they’re going to let you know,” Hieron told MMA Junkie Radio.

“We were in the belly of the beast. We’re in the UFC crowd. They’re the most hardcore fans in sports arenas. So, just to get the crowd going and get them all riled up, it was a great experience.”

Hieron's real-life UFC run lasted four months as the now-retired welterweight lost against the likes of Jake Ellenberger and former world champ Tyron Woodley.

This was actually Jay Hieron's first time stepping into the UFC Octagon since losing to 'The Chosen One' more than a decade ago.
