I saw this in New York a few years ago and thought it was hilarious, so I convinced Keith we should take a chance on the Mesa Encore Theatre production. The result was amusing but not at all up to the earlier standard which was tight, fast and furious, and hilarious.
This production was funny, and clearly appealed to the vast majority of the audience, but it was a bit slow, repetitive and slapstick where it should have been farce. The lead actor, Kent Burnham, playing the part of Richard Hannay was very good. His professional experience showed through. The rest of the cast were competent, but not great.
I may be misremembering, but I think the big difference between the two productions that I have seen is that the NY cast played the lines straight, as though everything were completely logical. This cast played to the audience, with many nudge, nudge wink ,wink gestures to make sure we got the joke. The result was amusing, but not anywhere as funny.
