I just watched the trailer for this. Not sure what to think about it yet. With John Cleese in there it should be funny. Seems more slapstick type of humor possibly - guy getting stuck in a window. Think I might give this a miss for the time being.
From what I can see this might have worked as a televisual play like they used to do for things like Natural Causes, Armchair Theatre etc but in present formot it feels stretched and a waste of the talent involved.
