Anthology series.
This Love Affair was series of plays looking at new relationships all written by Australian writers. This Love Affair is sometimes called a trilogy, but contemporary newspapers and television guides state that it was a series of thirteen individual plays.
So far, the broadcast details have been traced for the first twelve episodes, although the available information is, in some cases, limited to broadcast date, with no cast, crew, or author details.
The reviewer for the Australian Women's Weekly noted that the series:
began by looking moderately promising, and then settled to hours of harrowing for Sunday night viewers foolish enough to watch.
Generally the stories were lull of misunderstanding women and insensitive men, or vice versa. The acting was awful and the entertainment value could be compared to those ghastly endured experiences that Pollyannas describe as 'character building.'
('Let's Have Some Happiness', Australian Women's Weekly, 31 July 1974, p.10).
The series ran between 14 April and at least June 1974.
(Further, this series was itself the first of 'a trilogy of anthologies on love and was followed by Out of Love (a quartet of plays all written by Brian Faull) looking at marriage breakdowns and the divorce in a trilogy called Separate Ways'.)
Although some scant information is available about This Love Affair and Out of Love, the digitised script at the National Archive suggests strongly that Romeril's episode was originally considered for the series Time for Love which included his The Best of Mates.
