Be literal and honest, but be vague.
For example:
An alien goes to earth where he poses as a newspaper writer to distract everyone from the fact that he wears tights.
Answer: Superman.
Now you try it but don't put the answer to see if we can guess the movie.
a nasty yet attractive woman marries two men she doesn't love and gets screwed in the end.
shareHint?
My only guess was Gone with the Wind, but she doesn't marry Rhett and I don't remember if she gets screwed in the end or not.
She was married to Rhett and had a child. Rhett walks out on her at the end...........Frankly my darling. She was also married to Charles (killed in the war) and Frank (killed post war). She didn't love either of these guys but she did love Rhett but realized it too late.
shareI thought she married Ashley, and don't remember Frank at all. It's been a long time since I've seen it 😀
Fiddle dee dee.
