Sometimes American comedies make the mistake of giving away the best joke too soon. How many times have you gone to see a film based on a great preview only to find out the entire film was based on one gag? British comedy doesn't work that way. "Run For Your Wife" may not have you laughing out loud until 20 minutes in but be patient, its all part of the plan. Ala Lucy, London cabbie John Smith (John Messersmith) has some explaining to do. Seeing as he has two wives he decides to lie instead. Everything was going along swimmingly for Smith until he decided to rescue and old lady who was being mugged. A bonk on the head leaves him a bit scatterbrained, and he mistakenly reveals two different addresses to the Wimbledon Police and the local hospital. The mistake lands him at the wrong flat with the wrong wife on the wrong day.
