22Jurassic Park

In Jurassic Park (1993), the insect trapped in amber and which made the cloning of dinosaur possible was actually an elephant mosquito. Technically, it's the only mosquito that doesn't suck blood, so in theory, cloning dinosaurs with its help shouldn't have been possible.
23The Big Lebowski

The Big Lebowski secured rights for the song Dead Flowers (closing credits) when rights owner and Rolling Stones manager Allen Klein, who was asking $150,000 heard the line "I hate the fuckin’ Eagles, man!'' Klein stood up and said, ‘That’s it, you can have the song!'
24Planes, Trains and Automobiles

The R-rated film Planes, Trains and Automobiles would have been rated PG if not for the scene where Steve Martin says "fu*king" 18 times in one minute. Despite the rating, it is the only time in the movie where the word is used.
25Shrek

Shrek was originally given a thick Canadian accent by actor Mike Meyers. However, after the animation had begun and the dialogue almost finished, Meyers decided the character would be better portrayed with a Scottish accent. The film had to be re-animated and this little change cost over $4 million.
