It is sometimes customary for the star of a film to write and/or direct the picture under a pseudonym. John Calvert reversed the tradition in Dark Venture. He billed himself as John Calvert on the production credits, but was listed as John Trevlac (spell it backwards) in the cast list. Trevlac/Calvert plays an explorer in search of the elephant's graveyard (a mythical locale seemingly so sacred that, to paraphrase satirist Jules Feiffer, one can envision the elephants taking Final Instructions from the church). Upon reaching his goal, Trevlac must contend with half-mad claim jumper John Enidarrac...er, John Carradine. ~ Hal Erickson, Rovi
