Hayden appeared opposite Robin Askwith, her then-boyfriend, in the popular sex comedies Confessions of a Window Cleaner (1974), Confessions from a Holiday Camp (1977) and, with Fiona Richmond, in Let's Get Laid (1978); as well as the obscure cult film Queen Kong (1976). She also shared the stage with Askwith, in Richard Harris and Leslie Darbon's farce Who Goes Bare. Hayden and Richmond had previously appeared together in the thriller Exposé (1976), which was known as Trauma in the USA and House on Straw Hill in Australia, and banned in the UK as a video nasty. In a documentary on the DVD of The Blood on Satan's Claw, Hayden says that Exposé is the only movie she regrets making and was not the film she had made originally.
