I had ordered the marvelous Oh Mr Porter from my DVD rental firm and was sent Convict 99 by mistake. This is not a patch on Oh Mr Porter; indeed I found it alternately boring and pathetically unfunny. It might have been a hoot in 1938, but it has not worn well. The backchat between Will Hay, Moore Marriott and Graham Moffat, hilarious in Oh Mr Porter, is here irritating and totally unfunny. The story is, of course, completely unbelievable, but that doesn't matter if the situations are comic, or the dialogue amusing. I just thought the whole thing a total waste of time. I'm trying to get Oh Mr Porter to reassure myself how funny Will Hay and his team can be. A complete dud.
