film typical of sixties stories with gays SPOILERS
This was the first film to show a gay bar. Some may think wasn't that daring?
They would applaud Otto Preminger for having the courage to break down an old taboo.
But when Don Murray's senator walks into there, in search of his old Army buddy, the first men he sees are effeminate types looking him over. The bar is shown partly in shadows. This is to show that what happens there is shameful and must be hidden. It is supposedly not a normal, healthy place where any real man would want his twenty-one year old son to go to learn how many drinks he could hold. Murray looks at it and it's all male patrons and is horrified. He runs away in fear and disgust. His gay ex friend runs after him but the senator knocks him into a gutter. That would be exactly where he belongs, according to Hollywood then, never thinking that gay men bought film tickets.
So, this movie was an innovation for showing gay characters. But the senator kills himself in shame and self-loathing. This was a convenient way of getting rid of homosexuals as the Production Code was being lifted.
