Worth watching only for Bogart

It is hard to imagine how Bogart kept a straight face while making this film. The plot is absurd, with coincidences and chance encounters galore, the scenery and settings ridiculous and the characters unbelievable. It must be one of the worst films he ever made. Even the dialogue is false. However if you want to see how a great actor overcomes obstacles and almost makes you suspend disbelief(even he can't make you do this completely surely?) it is worth a punt.
