Dick Tracy Meets Gruesome

The fourth and final RKO Dick Tracy feature, and the only one to star Boris Karloff. A convicted killer called Gruesome gets his hands on a canister of experimental nerve gas that freezes anyone who breathes it mid-action, and uses it to stage a bank robbery in which the customers and staff stand paralyzed while the vault is cleaned out. Tess Trueheart witnesses the robbery and barely escapes, bringing Dick Tracy onto the case. Ralph Byrd, who had played Tracy in the Republic serials, returns to the role here. Karloff's presence gives the picture a jolt of real menace that the series had lacked, and the gas gimmick is a neat piece of B-noir plotting. Released in 1947, the film is in the public domain in the United States.
