who at one point becomes the chief suspect in a series of gruesome axe killings; Patrick Magee and Luana Anders led the supporting cast. Many years later, Campbell would provide an audio commentary for the film's DVD release. Campbell also starred in another Corman-produced horror yarn. Filmed in 1963 in Yugoslavia under the title Operacija Ticijan, again with Magee in the cast, the film was never released in its original form. It was re-edited, re-dubbed, and briefly shown on television as Portrait in Terror. Years later, additional footage was shot in California, first by Jack Hill, then by Stephanie Rothman, transforming what was once a spy thriller into the story of a vampire stalking the streets of Venice, California. Retitled Blood Bath, although it also became known as Track of the Vampire, the film received a limited theatrical release in 1966. Campbell also filmed The Secret Invasion in Yugoslavia that was directed by Roger Corman and written by his brother Robert Wright Campbell. Campbell was the only one of the team of commandos not given screen credit above the title. One year previously in 1965 he landed a supporting role as a reporter in the classic suspense horror; Hush...Hush, Sweet Charlotte. In Blood Bath Campbell's character was an artist who killed women and hid their bodies inside his sculptures; he is also a vampire who can freely walk during the daylight in search of victims. However, the fanged vampire was confusingly played by another actor who did not resemble Campbell. Like Dementia 13, the film has managed to develop a following despite its deficiencies. In the early 1990s, Video Watchdog magazine devoted lengthy articles in three separate issues painstakingly detailing the convoluted production history of this strange but fascinating movie. Campbell had guest starring roles in the Star Trek franchise, appearing first as the mischievous super-being Trelane, in an episode of the original series called "The Squire of Gothos". Campbell also appeared twice as the Klingon Captain Koloth. Campbell first played Koloth on the original Star Trek series in the episode "The Trouble with Tribbles". He reprised the role on the series Star Trek: Deep Space Nine episode entitled "Blood Oath", some thirty years later. Campbell appeared at several Trek conventions in the 1980s and 1990s. His last appearance was at the convention organized by Creation Entertainment at the Las Vegas Hilton in August 2006. Personal life and death Campbell
