I haven’t seen it, but find it hard to believe that Hollyweird “stars” can’t get laid on their own.
It was all about ‘secrecy’. They went to Bowers because he had the low profile and contacts, and the ability to keep their secrets safe.
The rumors about Cary Grant, and all the others were tabloid fodder, but the real story was Scotty knew all and didn’t tell until they were all dead........................
Much of Bowers’ clientele had um, “special tastes”. This was in the buttoned-down 40s and 50s when being gay had both legal and social consequences. Big name stars had to be extra-careful and he specialized in being discreet.
