If you were expecting a gloriously unapologetic period film bonanza in the upcoming film based on Ubisoft’s hit video game series Assassin’s Creed, think again. In an interview with IGN, executive producer Pat Crowley revealed that, unlike the video games, around 65 percent of the film would be set in the present day, and only 35 percent running around 15th century Spain.

This could be considered a spoiler, but it’s also possible the filmmakers warn moviegoers before they have a chance to be disappointed in the cinema.

Michael Fassbender, who plays the film’s protagonist, noted to IGN, “This isn’t a video game that we’re making. We’re trying to make a cinematic experience, so there are new things that we have to introduce.”

The film is scheduled to open globally on December 21.
