I can see why movie studios would want to put the clamps down on people who try to put entire movies up on YouTube, but leveling copyright objections at two-minute clips from movies just seems silly. Those clips, when used in blogs and Facebook-sharings and Twitter feeds, constitute free advertising for their movies. If I had a nickel for every time I've posted a clip from some movie and had someone comment afterwards along the lines of "Hey, I've never seen that but now I think I will!", I could probably buy a dinner at a nice restaurant, like Mendy's.
(Which is my way of saying that Universal needs to stop blocking clips of Love Actually. Wankers!)
