Jean-Marc Lofficier (French: [lɔfisje]; born June 22, 1954) is a French author of books about films and television programs, as well as numerous comics and translations of a number of animation screenplays. He usually collaborates with his wife, Randy Lofficier (born Philadelphia, Pennsylvania, U.S., on February 3, 1953), and the reason why credits sometimes read "R. J. M. Lofficier", after the initials of both spouses.
