Showdown
"Showdown" - A black-and-white Western showing in New York in 1994.
History
The trio were thrilled by it when it came out, particularly Broadway. Unfortunately, his overenthuasiasm about a gunfight in it led to his accidentally shooting Elisa with her own gun afterwards.
Other
"Showdown" presumably showed at the same theatre where the Trio later watched "Bambi".
