BEHIND THE SCREEN, released this week in 1916

Goliath, the stage hand, and his assistant, David.

Charlie manages to carry a dozen chairs and a piano at once.

"Stage hands lunch hour." Charlie uses bellows to shield himself from Albert Austin's smelly onions.

Charlie discovers the new stage hand is really a girl (Edna).

He promises to keep her secret.

When Eric sees Charlie kissing the new stage hand, he makes fun
of him by doing an effeminate dance. These blatant references to homosexuality were very
risqué at the time. 

"The comedy department rehearses a new idea"--a pie fight.

After a fight with Charlie, Eric falls into the trap door that has been rigged with explosives
by the striking stage hands. 

Charlie and Edna congratulate each other on their escape.
