Life moves pretty fast.

And while filming Ferris Bueller’s Day Off in 1985, star Mia Sara hoped it would move even quicker. The 59-year-old, who played Sloane, revealed that she struggled to work with director John Hughes.

“I don’t really give interviews because making Ferris Bueller was not that good an experience for me,” Sara told The Times in an interview published on June 20. “But I’m very aware of what a precious thing this movie is, and I don’t want to disappoint people. But I didn’t get along well with John.”

The Timecop actress—who was only 17 when she was cast in the 1986 teen comedy—chalked it up to a personality clash, calling Hughes a “strange guy.”

“He wanted us all to hang out together and to introduce us to the French New Wave films,” she recalled. “But the others were seasoned actors and I was a snotty New York kid and had seen all those movies, so he was frustrated in that desire. I didn’t have the emotional maturity to deal with other people’s egos, or my own.”
