In 1968, Taylor starred in two films directed by Joseph Losey – "Boom!" and "Secret Ceremony" – both of which were critical and commercial failures. The former, based on Tennessee Williams' "The Milk Train Doesn't Stop Here Anymore", features her as an aging, serial-marrying millionaire, and Burton as a younger man who turns up on the Mediterranean island on which she has retired. "Secret Ceremony" is a psychological drama which also stars Mia Farrow and Robert Mitchum. Taylor's third film with George Stevens, "The Only Game in Town" (1970), in which she played a Las Vegas showgirl who has an affair with a compulsive gambler, played by Warren Beatty, was unsuccessful.
