Flim Flam Films is a 1927 silent animated short subject featuring Felix the Cat.
[1] Felix tries to put Inky, Winky and Dinky to bed as part of their nap time but, apparently, they are angry and bored.
Their disguise, however, does not keep them covered for long when a guard at the cinema spots some bizarreness on top because the tail of Dinky, one of the kittens that was pretending to be the man's hat, ends up getting loose from him.
Felix takes his tail and takes it off himself and uses it as a cane, striking a pose similar to Charlie Chaplin, but when he, in the film gets attacked by a lion, the angry kittens rush forth and assault the screen, probably feeling like Felix had actually been attacked by a lion outside of the movie, therefore, causing a commotion from the audience.
The characters in the film, however, appear upside down but Felix is able to make quick adjustments, minus the ballet dancer and the female swimmer, the ballet dancer's clip is not upside down but has a bizarre view, while the female swimmer's clip appears in normal format.
