10 Actors Tricked Into Doing Famous Movie Scenes

10. Willy Wonka & The Chocolate Factory - Actors Not Told About The Tunnel Scene

"There's no earthly way of knowing, which direction we are going..." aren't just the lyrics mumbled by Gene Wilder during the infamous Tunnel of Terror scene which goes down in Willy Wonka & The Chocolate Factory, they were also likely the thoughts shared by the actors experiencing that traumatising boat ride with him.

Throughout much of the making of this now-iconic feature, director Mel Stuart insisted on not showing or telling the actors experiencing Wonka's world for the first time much about the factory or the mysterious figure behind it. So, on top of only being shown the colourful Chocolate Room before the shooting of the actual scene, Stuart also didn't inform his cast exactly what was incoming once they sat down for a ride down the chocolate river.

As the lights began to flicker and Wilder's improvised performance only grew in terrifying intensity, the children in particular were pretty spooked by the surreal set of events. This made for some authentic reactions when it came to the finished product, but it also made the cast wonder whether anyone would want to come and watch a movie showcasing this mad man.

According to Denise Nickerson, who played Violet in the film:

"I had not anticipated that, it was not in the script that he was going to go off on that tangent. I was completely speechless. I thought, nobody is going to come and see this movie this (Wonka character) is a nutjob. But good thing I’m not a producer, right?”
