In 1940, the Marx Bros. appeared in one of the earliest cinematic western comedies, an overlooked picture called Go West. It comes from pretty late in the post-Zeppo era, a run of pictures often considered inferior to when the brothers were at their peak. Still, even without Zeppo — who was a crucial part of the Marx formula, a secret sauce if you will — the Brothers made a pretty admirable chunk of films after their Paramount days. Go West is one of them, even if it never quite matches the heights of the comparatively Zeppo-less A Night at the Opera.
