The Forbidden Room

Prepare to take fantasy experimental films to a whole new dimension. This 2015 genre busting film by Canadian director Guy Maddin is a nesting doll of plots centered around a submarine crew that can't surface without exploding. And it gets weirder from there.
The movie is available on Kanopy.
