I watched an interview last night with Anneke Wills. When she was 21 in 1962 she married the actor Michael Gough, who was born in 1916. Maybe young ladies in those days didn't mind a bit of DILF?That was always the theme in 1940/1950s films. You’ll inevitably get some middle aged bloke (usually a WW2 pilot or destroyer captain tap off with a 19 year old nurse) As an example, see the Douglas Bader film (I can’t remember its name).
I really wish such things did happen, but they don’t, not in real life, otherwise I’d be sewing pilot wings on to all my T-shirts.
