Batman Returns

The production wanted to use King Penguins, but the only tame ones in captivity were at a bird sanctuary in the Cotswolds, deep in the English countryside. So the birds were flown over to the States in the refrigerated hold of a plane. They were given their own refrigerated trailer and swimming pool with half a ton of fresh ice every day, and had fresh fish delivered daily straight from the docks. Even though the temperature outside frequently topped one hundred degrees, the entire set was refrigerated down to thirty-five degrees. The birds also had an around-the-clock bodyguard. The birds clearly enjoyed the experience as, following their stint in Hollywood, most of them had mated and produced eggs, the sure sign of a contented penguin.

When the Mayor of Gotham City says "Where is that insufferable son of a bitch?" you can see Commissioner Gordon mouthing his line.

Of the four films from the Tim Burton/Joel Schumacher Batman franchise, this is the only one in which the opening credits sequence does not feature/use the Batman logo or a variation on it.

In the UK the film was cut by 9 seconds at its cinema release. One cut was of a clown swinging nunchakus, the other was of Catwoman putting some spray-paint cans in a microwave to start an explosion at a department store. These cuts also applied to all pre-2005 VHS and DVD releases. In 2005, the film was resubmitted for the special edition DVD release. The BBFC downgraded the certificate back to the original 12 certificate (which was not possible in 1992, when the 12 certificate was cinema only), and waived the cuts to the chain-sticks scene, but the aerosol in the microwave scene remained cut on the grounds that it was a potentially dangerous imitable technique. Various extra features being rated 15 caused the overall category of the DVD to be 15. The resulting cuts meant that the audio commentary was dropped from the UK release (probably because it would have been out of sync), although it is still mistakenly advertised as present on the DVD packaging. All previous BBFC cuts were finally fully waived in 2009 for the Blu-ray release, and the film upgraded to 15.
