Banner's film acting began in 1964 with
Spider Baby, also starring
Sid Haig and
Lon Chaney Jr. and directed by
Jack Hill. However, the film was tied up in litigation and was not released until 1967 under various titles, including
Attack of the Liver Eaters,
Cannibal Orgy, and
The Maddest Story Ever Told. The black and white feature quickly faded from view.
Spider Baby became known largely through the efforts of Los Angeles cult film resurrectionist
Johnny Legend. The film tells the story of the Merrye family, who suffer from a
degenerative disease. While
Spider Baby remained in legal limbo, Banner was uncredited in
Deadlier Than the Male (1966), a British mystery about two female assassins. In 1967, she played Wendy, a wholesome teenager, in ''
C'mon, Let's Live a Little, one of the last of the Beach party films, and as Caroline in the Spaghetti Western The Stranger Returns''. In the psychedelically paranoid spy spoof ''
The President's Analyst'' (1967), Banner played a flower child named "Snow White" who temporarily rescues Dr. Sidney Schaefer from a combined conspiracy of the American CIA, the Russian KGB, and The Phone Company (referred to cryptically as "TPC"). She was featured in several episodes of
Jack Webb's police-procedural shows,
Dragnet and
Adam-12, usually playing clueless teenagers and spaced-out daytrippers. Banner performed in several movies and TV shows in the late 1960s and early 1970s, including
Shadow Over Elveron (1968) with
Don Ameche and
Adam-12 co-star
Kent McCord. In
The Stranger Returns (also known as
Shoot First Laugh Last and
Un Uomo, Un Cavallo, Una Pistola), Banner played the pretty daughter of a corrupt postal official who falls into the hands of banditos, only to be rescued by The Stranger. She was also featured in
Hunters Are For Killing (1970), an early
Burt Reynolds movie. She later appeared in episodes of the television shows
The Bold Ones and ''
Cade's County''. She had an uncredited bit part in
Christian Marquand's 1968 film
Candy, but her scene was deleted from the final print. ==Later years==
