Boogie Nights (1997)

Revealing mistake: In Dirk's first sex scene with Amber they are both supposed to be naked except for their shoes. At the end of the scene Amber sits up on the table on which they had sex as a female stage hand wraps her in a robe, and you can see she is wearing black panties.

Dirk Diggler: I'm Dirk Diggler! I'm the star! It's my big dick and I say when we roll!

Trivia: Burt Reynolds turned down the role of Jack Horner several times, he finally agreed to do it reluctantly. He hated the film, and thought his acting was terrible and that the film would be a total bomb, so he publicly denounced it. He even fired his agent. However, when it came out it was hailed as Reynolds' comeback role, and he was nominated for an Academy Award. He then changed his opinion of the film drastically.
