the lampshade in that trailer is amazing

When I saw the movie in its original theatrical release in 1978 (I was 14) a girl in the audience screamed "DON'T DO IT SUPERMAN!" when Chris Reeve leaned in to kiss Michael Caine. It was hilarious even to a closeted 14 year old fag boy.

See, it's little subtleties like that which are completely lost on these lunatics. Really, the whole world is lost on them too.

"Hey, Ira, what are you writing there, honey?"
"It's this new play I'm working on. It's called Deathtrap."
"Ooh, exciting. What's it about?"
"It's about a playwright who conspires to murder his wife and run off with his gay lover. Do you want to read it?"
"No, I have to go now."

My high school did Deathtrap in 1979 before the movie came out. I'll never forget the first read through when the kid who was going to be playing Sidney said the line, "you know I love you, Cliff," and then immediately said: "what is this fag play?" Our drama teacher gave a little speech about tolerance and humanity and good drama, and the show went as written, except the two boys hugged instead of kissed. And this was conservative Orange County more than 30 years ago!
