Monty Python’s Eric Idle just did an interview with The New York Times in advance of his new memoir, Always Look on The Bright Side of Life: A Sortabiography. The chat is filled with insight, heart, and plenty of affable grouchiness, but of particular note is the confirmation of a story that’s long swirled around a film with which Idle has no part: The Empire Strikes Back.
In a 2015 interview with The Daily Beast, Fisher recounted a late night party with the Rolling goddamned Stones at Idle’s house that, unsurprisingly, resulted in her and Empire co-star Harrison Ford getting so tanked on something called the “Tunisian Death Drink” that their drunkenness bled into the next day’s shoot.
