I am no legal professional, but if an Actor, Actress or Director says something slanderous on a commentary track like 'Our wardrobe department stole all the cloths from a local gym to save money!' Then no 'for entertainment purposes only' message is going to protect them from an order to pay damages to the wardrobe company's image and loss of business.
I understand that managers follow what advice the legal department gives them and that the legal department is trying to cover themselves in a very sheepish manor, but you wouldn't find a legal disclaimer like that at the start of an encyclopaedia.

In July I Posted about how Amazon cleaned customer Kindles of a few novels. Well I am sure they thought they where legally covered, but they also deleted one Justin Gawronski's Summer Homework. He is as American tradition dictates, suing Amazon for damages. And rightly so because that kind of thing might conform to the letter of the law by Amazon giving itself the right to do that kind of stuff in it's terms of service, but it is very unreasonable.
