Star Trek: First Contact

From MAlf

In this movie, Picard decides to follow a Borg cube back to the 21st century, where Data was later assimilated, Troi got drunk, and he was killed by a bizarre bunny that appeared out of nowhere.

In hindsight, this is actually the plot for Donnie Darko. Our bad.

First Contact was also the name of an episode of Star Trek. I think it was the one with Picard, which they expanded to make the movie. You can see the bits they added.
