Al Adamson (July 25, 1929 - June 21, 1995) was a prolific director of B-grade horror films throughout the 1960s and 1970s.

After assisting his father in making the 1963 movie Halfway to Hell, Adamson decided to work in the motion picture industry. Three years later, he and Sam Sherman founded Independent-International Pictures, which became the vehicle for the many movies he directed. Among them are Psycho-A-Go-Go (later reshot as Blood of Ghastly Horror), Satan's Sadists, Horror of the Blood Monsters, Dracula vs. Frankenstein, and Five Bloody Graves.

After Adamson was reported as missing in 1995, law enforcement officials discovered his murdered corpse beneath the concrete- and tile-covered whirlpool bath in his newly remodeled bathroom. The perpetrator was his live-in contractor Fred Fulford. After being apprehended in Miami Florida, Fulford was charged with and convicted of murder, and was sentenced to twenty-five-years in prison. Mr. Adamson was the husband of actress, Stevee Ashlock.

Although it's very unlikely that his admittedly cheap'n'cheesy films will ever be acknowledged as true works of cinematic art, director/producer/screenwriter Al Adamson did nonetheless make a slew of entertainingly trashy low-budget exploitation features for the drive-in market throughout the 60s and 70s. Al was born on July 25, 1929 in Hollywood, California. He was the son of actress Dolores Booth and actor/director Victor Adamson, who appropriately enough specialized in shoddy poverty row 30s Western programmers. Adamson's first foray into filmmaking was helping his father as director and producer on the movie "Halfway to Hell." In the mid 60s Al founded the prolific grind-house outfit Independent-International Pictures with producer/distributor Sam Sherman. Adamson cranked out a bunch of flicks in every conceivable genre: scuzzy biker items ("Satan's Sadists," "Hell's Bloody Devils," "Angels' Wild Women"), gritty Westerns ("Five Bloody Graves," "Jessi's Girls"), silly soft-core comedies ("The Naughty Stewardesses," "Blazing Stewardesses"), funky blaxploitation ("Mean Mother," "Black Heat"), ridiculous science fiction dross (the gloriously ghastly "Horror of the Blood Monsters"), two Jim Kelly martial arts action outings ("Black Samurai," "Death Dimension"), lurid horror fare ("Dracula Vs. Frankenstein," "Brain of Blood," "Nurse Sherri"), and even a tongue-in-cheek soft-core science fiction musical ("Cinderella 2000"). Moreover, Adamson served as a producer for both the exciting Fred Williamson blaxploitation vehicle "Hammer" and the acclaimed made-for-TV drama "Cry Rape." The casts of Adamson's movies were made up of oddball, but enthusiastic amateurs and faded name thespians who include Kent Taylor, Russ Tamblyn, Lon Chaney, Jr. and the ubiquitous John Carradine. Al frequently gave his wife Regina Carrol sizable parts in his films. Moreover, Adamson was a mentor for future schlock feature directors Greydon Clark and John "Bud" Cardos. Al was also instrumental in launching the career of ace cinematographer Gary Graver. In addition, Adamson kept fellow top cinematographers Laszlo Kovacs and Vilmos Zsigmond employed in their early salad days. Al Adamson's life came to a brutal and abrupt untimely end at age 66 when he was murdered by live-in contractor Fred Fulford on August 2, 1995.
