Monkeys banned from actorly activity

Anger at bid to fly monkeys to Australia for Pirates of the Caribbean film | World news | The Guardian

Animal rights activists object to a couple of pampered monkey actors being flown over to Australia for a movie.  Funny that millions of cats and dogs aren't rendered insane by aircraft flights, and one would also assume that these monkeys have travelled that way before.   I think animal rights activists are starting to have trouble finding things to object to...

But what is this about?:

The Department of Environment has proposed conditions on the import
permit, stipulating that the monkeys be used only for filming, that they
should not be allowed to have sex with each other or have contact with
monkeys of any species.

Now that's cruel.
