There is an ad on TV (Nextel I think) about a movie sequel being "Green lit". I have seen the ad a million times, but just now noticed a detail. In the background in the last shot of the ad, they are in a producer's office and one of the fictitious movie posters on the wall is for "Invisible Thunder". That title cracks me up. If you don't get it, just think about it a bit, or leave me a comment. :)
