Michael J Fox has filmed a cameo for new Netflix time travel film See  You Yesterday.

The film follows two teenagers who invent time travel machines for their high school science project. Fox plays their inspirational teacher.

The film is directed and co-written by Stefon Brisol, who counts Spike Lee among his mentors.

“We had another really great cameo that we wanted to go for. Unfortunately, he was unavailable by the time we needed to book somebody,” Bristol tells EW.

“I was all set about who was gonna be it and we can’t get him. And I thought of another actor in the movie, and someone said, ‘Why don’t we just go with Michael J. Fox?’ I was like, ‘Alright cool! Let’s go with that.’”

See You Yesterday will premiere on Netflix on May 17.
