Have you ever seen a movie that's now considered lost?

Not totally lost but almost impossible to find:

Alexandre Le Bienheureu (Happy Happy Alexander) starring Philipe Noiret as a lazy farmer who just wants to sleep all the time.

Gigot starring Jackie Gleason as a deaf/mute French janitor

It took me years to find copies of these films, someone from the old boards helped me locate copies.

p.s. I have no idea why part of this post is in Bold Type.
