Not being very familiar with iMovie, I had it import all the movies on my Mac. I noticed my drive space might have suffered for it. How do I disassociate all those movies from iMovie to reclaim that lost drive space?
iMovie imports can take up a good bit of space if you copy the files on import, instead of moving them. Luckily, you can easily remove these disk-hogging files with just a few clicks in iMovie.

Clicking Delete Unused will leave currently in-use videos alone.
After opening the application, Command-click on all of the events in the Events Library you want to remove, and then press Command-Delete on your keyboard. A new dialog will pop up, with two buttons, one labeled Delete and one labeled Delete Unused. Clicking Delete Unused will delete any of the selected events that are not currently part of an iMovie project. However, if you wish to delete all video files in iMovie, select Delete to delete all selected event videos.
