When Lionel Wigram decided to make a movie about Sherlock Holmes, he wanted to make sure the studios understood his pulpy vision. So he partnered with comics artist John Watkiss to create comic book-flavored concept art. Possible spoilers inside.
Wigram had Watkiss, who has provided artwork for Deadman, Sandman, and Conan, to bring his action comics style to Sherlock Holmes. Wigram wanted to create a visual pamphlet so that studio execs understood the sort of story he wanted to tell. Although some outlets have erroneously reported that Wigram and Watkiss collaborated on a comic, Wigram did have Watkiss illustrate the story, sans text. This series of illustrations then served as a key component of Watkiss' pitch.
The illustrations are currently on display and available fore sale at Nucleus Studios in Alhambra, California.
