Collaborate and work on an imovie with another person

Assuming that both accounts are on the same computer, you could try opening the iMovie library in Account #!, make your edits, close iMovie, and then open the iMovie library in Account #2. I've not tried this, so don't know if it can be done.

Sadly, Apple has not added this feature to iMovie yet. Hopefully they will include it in a future iMovie update.
