WATCH: Michael Fassbender Gave a Prince an Erection Filming ‘Jane Eyre’

When Michael Fassbender asks to ride you, it’s impossible to say ‘neigh’.

Things got personal for the actor back in 2011 on the set of Jane Eyre when a horse named Prince became aroused every time that Mr. Fassbender mounted his back to film a scene.

“Dan, the horse handler, had to get on it and sort of canter him or give it a little trot,” he recalls on The Graham Norton Show“He’d sort of slap it … retract ‘it’ back in.”

That is, until it was time to ride again.

Kate Winslet revealed in an interview with RTÉ TEN that she would try to feed Fassbender Snicker bars on the set of Steve Jobsfearing that he was losing too much weight while filming the movie.”He got thinner and thinner on the film even though he would eat like a horse” she said. “I couldn’t believe it, I’d be like, ‘Your jeans are falling down again.'”

Takes a stud to know one.
