We've all heard stories of prima donnas on the set of films. Big shot actors that need to have each and every one of their whims met, or else they'll lock themselves in their lavish trailers, leaving the production in a free fall. Well it turns out the actors that were pampered the most on the set of Batman Returns were … the penguins. Not The Penguin. Actual penguins.
The production wanted to use King Penguins to add some flair to Danny Devito's dastardly Penguin character, but the only tame ones in captivity were held in a bird sanctuary deep in the English countryside. They flew the flightless birds to the US in the refrigerated hold of a plane, and housed them in two forty-foot trailers, each temperature-controlled and including a swimming pool, along with another 2,000-gallon pool outside. The perks didn't end there — they even had a round-the-clock bodyguard, who clearly had the best job ever.
Despite the temperature topping at 100 degrees in Burbank, California, where the film was shot, the entire set was refrigerated down to 35 degrees, which brought the AC bill to roughly a million bucks. Deal with that Keaton — the penguins were the real stars here! The majestic beasts must have enjoyed their trip to Hollywood, as it's reported that most of them mated and produced eggs, which is the easiest way to confirm a happy penguin.
