“Back to the Future” screenwriter Bob Gale has revealed that Donald Trump was the inspiration for Marty McFly’s arch nemesis Biff Tannen.

The revelation comes as part of a slew of nostalgic retrospectives on “Back to the Future Part II,” in which McFly (Michael J. Fox) and Doc Brown (Christopher Lloyd) travel to Oct. 21, 2015. Gale spoke to the Daily Beast about the similarities between Biff and Trump.

“We thought about it when we made the movie! Are you kidding?” Gale told the outlet when asked if he noticed Biff’s resemblance to Trump. “You watch ‘Part II’ again and there’s a scene where Marty confronts Biff in his office and there’s a huge portrait of Biff on the wall behind Biff, and there’s one moment where Biff kind of stands up and he takes exactly the same pose as the portrait? Yeah.”

“Part II” sees Tannen (played by Thomas F. Wilson) build a 27-story casino and gain political sway, which he uses to take over Hill Valley, Calif., where he insists on being called “America’s greatest living folk hero.”

Director Robert Zemeckis declared on Wednesday that there would be no additional “Back to the Future” films made.

“It is a well-made trilogy, and will stay that way,” he said.
