Henry Hull refused to take the role of a ''pretty man''
In order to be successful, things can get a little ugly.

While plenty of young actors pray for the day they win the role of a leading man, Henry Hull had far loftier ambitions. A character actor, Hill thrived on any and all unusual roles.
Of course, Hull's interest in the strange served him well, as it won him the role of Dr. Wilfred Glendon in the 1935 film, Werewolf of London. The terrifying character, part man and part wolf, rocketed Hull into stardom.
According to a 1935 article in The Daily Missoulian, Hull claimed that he would not take a "pretty man" part. Instead, Hull valued "parts you can sink your teeth into."
Hull wanted a hefty role, and he was willing to do the work that went along with it. According to another article in the Los Angeles Times, Hull spent six weeks researching werewolves in preparation for his role in Werewolf of London.
Hull also had a say in the special effects makeup that went into transforming the young actor into a terrifying creature.
"Here's the way I want to look," Hull told Jack Pierce, the make-up artist on set for the film. "Now fix me up to look like this on screen."
The extra effort was well worth it, as Hull's performance received rave reviews. "Henry Hull's portrayal of the werewolf, a man who periodically is afflicted with wolf madness, will be compared with Bela Lugosi as the vampire Count Dracula, wrote one article in The Tribune.
