I would say the vast majority, maybe even 100% of these outtakes, are Mutual. The footage when he is on the boat is from THE IMMIGRANT, which is perhaps his most famous short film. It's been a while, but I believe the pie fight stuff is from BEHIND THE SCREEN, and I know the footage towards the beginning where he's drunk and he's near a staircase is ONE A.M. because that's one of my favorites. Another Mutual give away is that the big guy with the fake beard is Eric Campbell, who was Chaplin's heavy only in the Mutuals. He died shortly after the Mutual series wrapped up in an auto accident.
