In 1985, Randy Lofficier completed Harry Love's Animation Writing Seminar at Hanna-Barbera, which led the Lofficiers to write a number of animation scripts for television series such as "The Real Ghostbusters" and "Duck Tales". They also began to write numerous scripts for a variety of comic books, often in collaboration with other writers, notably Roy Thomas and Marv Wolfman, for both Marvel Comics and DC Comics. Their best-known works include a trilogy of DC "Elseworlds" based on German Expressionism cinema incorporating characters such as Superman, Batman and Wonder Woman, the "Book of the Vishanti" back-up feature for "Doctor Strange: Sorcerer Supreme", two stories for Clive Barker’s "Hellraiser", and the "Tongue*Lash" series for Dark Horse Comics.
