Gia/YMMV

Crowning Moment of Funny: The morning after Gia and Linda make love. Gia wakes up alone in her apartment, and rushes out to the hallway to see Linda about to get on the elevator. Gia is still completely stark naked, but is unfazed when Linda points this out to her. Then the elevator opens. The facial expressions on the people inside the elevator are utterly priceless.
Everybody Remembers the Stripper: Some people only remember the film due to the lesbian sex scene and assorted nude scenes.
Ho Yay: Happens during an early photoshoot of Gia's, when she convinces two guys to make out with each other.
Retroactive Recognition: A much younger Mila Kunis plays Gia as a child.
Tear Jerker: Gia's death and the lead-up to it is an obvious one, but there are many others. Gia's reaction to Wilhelmina's death, Linda forcing Gia to choose between her and the drugs (made even worse when Gia chooses the drugs), Gia's rape at her drug dealer's hands...
The Woobie: Both Gia and Linda become this during the course of the movie.
