The idea of gassing Nazis as a humane cure came to me like a complete Albert Brooks comedy movie. Gotta have Rip Torn as a Nazi leader that is cured. This screenplay is extremely funny against the backdrop of Nazi hate. Kinda reminds me of the movie 'Defending your Life' against the backdrop of death.

Lots of how and why hijinks getting Nazis covertly into the arenas.

Iconic humor is the weapon I choose. :^)
