''Werewolf of London'' is a horror film released in 1935. Produced by Creator/{{Universal}}, it is the first werewolf film made in Hollywood.

While searching for a rare plant in Tibet, wealthy botanist Wilfred Glendon is bitten by a werewolf. After the incident he returns home to find his wife, more and more estranged from her neglectful husband, turning in her loneliness to her childhood sweetheart, Paul Ames. Glendon also meets the mysterious Dr. Yogami, who wishes to see the rare plant that Glendon has found, the ''Marifasa lupina'', as its blossoms form the only cure against werewolf transformation albeit a temporary one. Soon afterward, the remaining ''Marifasa'' is stolen and Glendon starts transforming on the nights of full moon. Each night people die and soon UsefulNotes/ScotlandYard is after him.

Werewolf make-up was designed by the legendary Jack Pierce, who later worked on that other well-known werewolf film, ''Film/TheWolfMan1941''.

!!This film contains the examples of:

* AbsenceMakesTheHeartGoYonder: As evidenced by Glendon and his wife.
* BeastMan: The design of the werewolves in this film is closer to this portrayal than the popular WolfMan design.
%%* BritainIsOnlyLondon
* CleaningUpRomanticLooseEnds: A continual feature of the Franchise/UniversalHorror films of this period. The character of Paul Ames is introduced largely for this purpose.
%%* DyingAsYourself
* EvilDetectingDog: Glendon's cat.
* {{Fainting}}: Aunt Ettie faints when she sees werewolf Glendon the second time.
%%* GenrePopularizer
* GratuitousLaboratoryFlasks: Botanist Wilfred Glendon has a table in his laboratory (otherwise devoted to electrical equipment, his moon lamp in particular) that features among other things an enormous retort, several huge graduated cylinders, racks of test tubes with cotton swabs as stoppers, bottles of various liquids and powders, and the expected conical flasks and beakers. He never uses them, and they appear to effectively just be set dressing.
* LadyDrunk: Both Mrs. Whack and Mrs. Moncaster.
* LoveTriangle: Among Glendon, his wife Lisa, and her childhood friend Paul.
* MeaningfulName: Mrs. Whack. She gets many whacks to the head from Mrs. Moncaster.
* NoPeripheralVision: While approaching the Glendon household, Paul somehow misses Glendon crouching on the porch roof before he attacks.
* {{Novelization}}: A surprisingly decent one by [[AwesomeMcCoolname Carl Dreadstone]] released as part of the Universal Horror Library in the 70's. It is told in the form of an extended flashback from Glendon's point of view so some characters like Paul Ames are barely present, and it has a different ending. Glendon and [[spoiler:Yogami]] try to have themselves hypnotized into not becoming werewolves. [[spoiler:It doesn't work.]]
* OurWerewolvesAreDifferent: Simple bullets can kill them, a certain Tibetan plant can counteract their transformations for a night, and they retain human intelligence (enough to think of putting on a coat and avoid crowds to stay hidden) even in the midst of bloodlust. As Yogami says, they have the worst traits of both men and wolves.

%%* SuperWindowJump
* ThingsManWasNotMeantToKnow: A priest answers this way when Glendon and his friend inquire of him about the valley where the ''Marifasa lupina'' is supposed to bloom.
%%* ThisWasHisTrueForm
* ThoseTwoGuys: Mrs. Whack and Mrs. Moncaster, two old lady drunks who tend to knock each other about on the slightest provocation.
* TragicMonster: We get two in this film, both Glendon and Yogami. The latter's characterization is oddly deep for one of these movies -- he does evil acts, and happily abandons Glendon to bouts of lycanthropic insanity, but at the same time he deeply regrets his own killings.
* TransformationSequence: Glendon gets several of them.
* VictoriousChildhoodFriend: Paul, by the end.
* WeirdMoon: The moon is full for four nights straight.
* WhatHappenedToTheMouse: Renwick, the guy with Glendon in Tibet. He is overcome by... whatever and Glendon just sort of abandons him and forgets he exists. He may have been one of the people at the party later but this doesn't answer where the heck he was when Glendon was getting attacked, or why Glendon just left him.
* TheXOfY
* YourCheatingHeart: One of the victims is Alf the zookeeper, who is about cheat on his wife with his girlfriend -- before Glendon kills said girlfriend. There's no mention of what happens to [[KarmaHoudini Alf]].
