The Woman in Red

The Adventure of Sherlock Holmes' Smarter Brother
What they share
Both films are directed by Gene Wilder, and they both carry the playful mood tag, and they sit in Comedy territory. If that's the register that drew you to The Woman in Red, the second film will land in a comparable space — through a different lens.
What The Adventure of Sherlock Holmes' Smarter Brother is
London fog. A telegram. Sigerson Holmes, overshadowed by his brother Sherlock, finally gets a crack at a juicy case involving compromising letters and a train to the opera. Mistaken identities and pratfalls ensue. Wilder's slapstick touches elevate this Holmes send-up.
