Written by Ray Galton and Alan Simpson, the series starred Leslie Phillips as wealthy womaniser Henry Newhouse (the English translation of "casa nova").

[1] Casanova '73 followed an episode of Galton and Simpson Comedy ("The Suit", 1969) for London Weekend Television in which Phillips played Howard Butler, a philandering businessman whose clothes are stolen whilst he is in bed at his secretary's home.

[3] Stanley Reynolds in The Times wrote that Phillips character "gets caught in the wrong beds in all the right comic places but it still does not seem to work.

"[4] Mary Whitehouse, of the National Viewers' and Listeners' Association and others objected to its risque contents.

This decision appears to have been taken close to transmission, as Radio Times, published a week in advance, still had the third episode as due to air pre-watershed, but The Times, published on the day of broadcast, listed the series as already having been moved in the schedule.
