Written by John Huston and Richard Brooks and directed by John Huston and filmed almost entirely on the backlot of Warner Bros. studios, Key Largo is a intricate character study of people under pressure. Starring Humphrey Bogart, Edward G Robinson, Lauren Bacall, Lionel Barrymore, Claire Trevor and many more excellent actors. We should also count the storm as a character. It plays a big role in setting the circumstances and the mood for everything that goes down in and around Key Largo. So grab some popcorn, close the blinds, and settle in for a trip to southern Florida during hurricane season. Enjoy!

There was a radio drama of Key Largo produced by Lux Radio Theater in 1949, starring Edward G. Robinson, Claire Trevor, Dan Seymour, and Edmond O'Brien.
