Paige VanZant -- Quits 'Kickboxer' Movie ... to Focus on UFC Fight

Paige VanZant's blockbuster movie debut has just been put on hold -- she's officially pulled out of the upcoming 'Kickboxer' movie ... so she can focus on fighting.

As we previously reported, PVZ had signed on for "Kickboxer Retaliation" ... joining stars like Mike Tyson and the guy who plays The Mountain on "Game of Thrones."

A bunch of people thought it could be the role that launched VanZant's acting career.

But Paige just put the kibosh on the project -- claiming the filming schedule interfered with training for her next fight with Bec Rawlings at "UFC on FOX" in August.

"I’ve recently declined to be in the Kickboxer movie because I want to be 100% for this fight and train 100%," Paige told ESPN.

"That movie filming was kinda gonna get in the way. We couldn’t get a date set that worked with my schedule.”
