Mr Denning Drives North [1951] [DVD]

John Mills looked thoroughly brooding in the startling red-and-black poster for this film, and as a result audiences might have found themselves somewhat disappointed by this resolutely genteel drama, which can't seem to make up its mind if it's a comedy.

Mills is excellent as the father who accidentally bumps off his daughter's devious lover, but the acting honours are stolen by Sam Wanamaker as the truth-seeking boyfriend.

There's also a supporting cast of stalwarts (including Bernard Lee, Wilfrid Hyde White, Herbert Lom and Freda Jackson) that makes this film, and other of its era, so watchable today.
