Tower of London is a 1939 black-and-white historical film released by Universal Pictures and directed by Rowland V. Lee. Sold to audiences as a horror film in the Universal cycle because of the teaming of Basil Rathbone and Boris Karloff, it is nothing of the kind, although Karloff does play a genuinely creepy character. It stars Rathbone as the future Richard III of England, and Karloff as his fictitious club-footed executioner Mord.

The film is based on the traditional depiction of Richard rising to become King of England by eliminating everyone ahead of him. Each time Richard accomplishes a murder, he removes one figurine from a dollhouse resembling a throneroom. Once he has completed his task, he now needs to defeat the exiled Henry Tudor to retain the throne.

The basic outline of the plot, aside from the character Mord, closely parallels Shakespeare's Richard III, though, of course, without the use of Elizabethan blank verse. George, Duke of Clarence (one of Richard's brothers) is depicted as something less than the tragically noble figure found in Shakespeare. Ian Hunter portrays Edward IV, who is not depicted here as the feeble, dying King found in Laurence Olivier's 1955 film version of Shakespeare's play.

The film inspired a 1962 remake starring Vincent Price (who plays the Duke of Clarence in this version). The remake was made on an extremely low budget, and placed far more of an emphasis on genuine horror.

Tower of London is a 1962 historical drama and horror film, starring Vincent Price and Michael Pate. It is the remake of the 1939 film of the same name, starring Basil Rathbone and Boris Karloff. Directed by Roger Corman, the film was produced by Edward Small Productions. The film also contained scenes that had been edited from the 1939 film.

In the 15th century Richard Duke of Gloucester, aided by his club-footed executioner Mord, eliminates those ahead of him in succession to the throne, then occupied by his brother King Edward IV of England. As each murder is accomplished he takes particular delight in removing small figurines, each resembling one of the successors, from a throne-room dollhouse, until he alone remains. After the death of Edward he becomes Richard III, King of England, and need only defeat the exiled Henry Tudor to retain power. Written by Doug Sederberg

This feature was planned for filming in color. On the Thursday before the Monday start of principle photography, uncredited executive producer Edward Small informed producer Gene Corman that it was going to be shot in black and white.

According to producer Gene Corman, he and his brother, director Roger Corman, considered leaving the production several times due to the cost cutting measures forced on them by uncredited executive producer Edward Small.
