Roman epic Caligula was released 45 years ago on August 14.

It was the first ever production created by Penthouse Films International, the big screen wing of the Penthouse magazine empire.

This was the 1970's, when the boundaries between arthouse and titillation blurred.

Mirren herself later said: "I was doing nude scenes from the moment I first started doing movies. I never wanted to show much boobs, but I thought, ‘Does it really matter?’ It seemed to be nothing to get your knickers in a twist over." Don't miss.
