Ball of Fire is just a lot of fun as a comedy. It's professors meets gangsters is a great set up and bolstered by some very enjoyable performances including Gary Cooper giving one of his most comfortable turns. The whole thing is just enjoyable and just is a great example of a screw ball comedy. What I really like is that the gangsters coming in does not make the comedy fade away since both Dana Andrews and Dan Duryea manage to be pretty funny while still being menacing. In addition the whole liar revealed part of the plot does not halt the story like it possibly could. It's just pure entertainment.
