[13] Leifert, called a "Baltimore horror maven" by Michael Sragow, appeared in several films for Dohler, did the costumes for Galaxy Invader, and was quoted as saying, "if you watch the films [I was in] carefully, they're really saved in the editing room.
"[2][14] Not wanting to resume his acting career, Leifert launched a "literate film appreciation magazine" named Movie Club with Dohler in 1993, where he managed the editorial side and Dohler the business side, commenting the following year that "it's fun to write about these films, because they're fun films.
"[14][2] He earned a law degree and taught at the George Washington Carver Center for Arts and Technology (also called the Carver School for the Arts) before leaving in 2000 to teach at Towson High School in Baltimore, Maryland.
