Trog is a 1970 British science fiction horror film starring Joan Crawford in a story about the discovery of a living troglodyte. The screenplay was written by Peter Bryan, John Gilling, and Aben Kandel, and the film directed by Freddie Francis. Trog marks Crawford's last motion picture appearance.
Set in contemporary England, the film follows Doctor Brockton (Joan Crawford) who learns that in the caves of the countryside, a troglodyte is alive and might be able to be helped and even domesticated. She gets the creature to the surface and attempts to train him, but runs into trouble as a few people oppose this, especially a local businessman afraid of negative commercial consequences, Sam Murdock (Michael Gough). Murdock frees the creature, leading to a rampage.

Trog was the second of two films that Crawford starred in for her friend, producer Herman Cohen; the first was Berserk! (1968). It also paired her with Michael Gough, who starred with Crawford in Berserk!
The film also features a small role by actor David Warbeck.
At the time of Trog's release, The New York Times panned the film but commented, "There is, however, a rudimentary virtue in Trog...in that it proves that Joan Crawford is grimly working at her craft. Unfortunately, the determined lady, who is fetching in a variety of chic pants suits and dresses, has little else going for her." 
Ned Daigle later commented, "Trog is truly ungodly. The performances are rotten, the Trog makeup is so bad it looks, at times, like it will slide right off the actor's face, and everything proceeds at a snail's pace to idiotic situations. It's really sad to see such a huge star [Crawford] be consigned to the Z-grade abyss of films like this. But, hey, a girl's gotta eat."
The film is listed in Golden Raspberry Award founder John Wilson's book The Official Razzie Movie Guide as one of The 100 Most Enjoyably Bad Movies Ever Made.
The film was released theatrically in both the United States and United Kingdom by Warner Bros. in 1970.
