Colby couldn't see the screen because the pain kept her eyes closed so her mother gave her a play-by-play of the film.
"Do you think you can hang on?" Colby's mother said.
"I'm ready (to die), but I'm going to wait for the movie," the girl replied.
At the end of the film, the mother asked if her daughter enjoyed the movie and Colby nodded yes, Lisa Curtin said.
Colby died later that evening, hopefully fulfilled in at least some small way.

It's a heartbreaking story to hear, but glad to see her wish was fulfilled. *manly tears* Much kudos to Pixar for being able to do this for her. Really touching and glad to see some good out in the world.
Also, if you were in a similar situation what movie would you see? I'd probably watch one my all time favorites Gladiator.
