XD It's "Si Versailles m'était conté," directed by Sacha Guitry. It's a rather famous movie. I came across these clips randomly on youtube, but as I mention above, I've never actually seen it.

The scene portrayed in the second video really irks me though. Basically, Robespierre says they should abolish the death penalty and all the other people at the table seem to be able to tell the future and answer ironically about what a "good idea" it would be (even though, to my knowledge, Robespierre was the only one of the figures represented who was actually against the death penalty) and how nice it would be if this abolition applied to them. *facepalm*
