This is a very touchy subject and one many theatre owners who do double will not discuss in public forums.
The art distribs are much more lenient and generally just happy to take a date. That of course changes when you are opening a big Miramax or Sory Classics picture. They can be just as hard ass as the rest plus they have less prints.
The majors are just plain no humour when it comes to doubling it. I had BV tell me "You'll either play it clean or pull the film." the day before the picture opened and we'd already advertised the pics and they meant it and implicit in the conversation was the threat that I'd be lucky to get another print out of them for a long time.
There's the rub: there's a lot of product but it's 10 people you talk to 95% of the time.
They really care about doubling! And they should. They've only got X days to make it happen. How would you like to spend 75 million making a pic and then have a shmo up in Maine doubling your pic? If they didn't fighjt it we'd double everything all the time!
Keep in mind the old Chinese saying, "The land is wide and the emperor is far away." Out of sight.... out of mind.
If you have close competion they are known to rat you out should they notice you doubling.
We use our own judgement and never double brand new stuff or something that is still hot. After that we start to get a little murky and plastiuc about the whole thing.
The last word is "Don't ask to double." They'll just say no. But you need to have a certain comfort level of experience that it's okay. In other words: doubling The Phantom Menace on the 2nd week should send a a warning flag to your brain. Putting Love's Labour's Lost on top of Chicken Run's 5th week early shows is a no brainer.
Some doubling is what makes it possible for us to back and fill, play catch up, sell tiks, and stay alive!
