Contrary to many an assumption, Tower of London is actually not a horror film, despite the dark and miserable English castle setting, the sight of Boris Karloff as club-footed executioner Mord, and the presence of Rowland V. Lee - a director perhaps best known for Son of Frankenstein (also released in 1939) - behind the camera. There's also the existence of Roger Corman's low-budget effort of the same name, which emphasised the horror and pushed genre legend Vincent Price (who also appears here in a smaller role) into the central role as the deformed, scheming Richard III. In fact, Lee's Tower of London is a historical drama, borrowing much from Shakespeare's Richard III but somewhat confusingly leaving out much of the detail.
Edward IV (Ian Hunter) sits comfortably on the throne of England after defeating King Henry VI (Miles Mander) and imprisoning him in the Tower of London. The feeble-minded former king wears a paper crown and lives in the hope that his son will return from exile in France to reclaim his crown. Edward enjoys combat practice with his formidable and cunning brother Richard, Duke of Gloucester (Basil Rathbone), while their soft, drunken younger brother the Duke of Clarence (Price) watches on enviously. Richard is an incredibly capable leader of men, but is way behind in the line of succession. He keeps a mini theatre hidden away where he plans to remove everybody in his way, and despite the many rivals who could challenge him for the crown, the hunchbacked prince will stop at nothing until he is seated on the throne.
Although not a horror, Tower of London certainly looks like one. The huge set created for the film became a staple of Universal, and the dark, chilling castle could be seen in many genre pieces produced by the studio in the following years. There's also a few brutal but bloodless murders, almost always involving Karloff's Mord, who is the closest thing the film has to a monster. Yet for the most part, this is more akin to Shakespeare, performed by a ridiculous wealth of acting talent. There are great turns by Hunter, Mander, Price (in only his fourth role) and Barbara O'Neil as Queen Elyzabeth, but the film belongs to Rathbone and Karloff, with the former even eclipsing Laurence Olivier's arguably hammy thesping in the 1955 film. Packing what is an incredibly complex tale into 90 minutes can confuse matters, but this is an entertaining, somewhat lighter alternative to Shakespeare's infinitely more grandiose work.
