The first set of Charley Chase Columbia shorts was good.
The second was even better.
There were so many outstanding efforts on the second set that it's hard to pick just one favorite. But some of the better ones were FROM BAD TO WORSE (1937), CALLING ALL DOCTORS (1937), THE BIG SQUIRT (1937) and THE SAP TAKES A WRAP (1939). There was something to like in all 12, though.
Having now seen all of Chase's Columbia's, the worst of the lot is an easy choice for me - MAN BITES LOVEBUG (1937), which was slow and just not all that interesting. Chase's best Columbia short is a much harder choice because so many were good. I might have to go with FROM BAD TO WORSE, but there are several that could fit.
