For about an hour it's a perfectly acceptable, if a little weak, little comedy for those who love Guinness and British film of the period. Then in the last third it goes progressively off the rails, culminating in a stupid ending. When you've heard about, seen, and loved other Ealing comedies but not this one, well, there's a reason. Big surprise for those of us who only know Yvonne De Carlo from The Munsters. She was a knockout.
