Maybe few movies (at least musical comedies) from the 1950s demonstrate old fashioned “heterosexism” as the 1955 Cinemascope romp “The Tender Trap” directed by Charlie Waters, music by Jeff Alexander.
Member the song, “Love is the Tender Trap.” My own father used to say, “One day, blue eyes will confuse you.” Now that might sound quasi-racist. My first roommate at William and Mary was befuddled by my non-reaction to normal porn. “You should be ….” And then, having someone deped on me this way was supposed to trap me, and remain exciting. It wasn’t.
I rather vaguely remember seeing this with mother and cousin, at a time when I was getting into movies. I think Cinemascope had just come to the neighborhoods then.
Here's another, detailed take on this movie.
