The Wizard of Oz
The Man Who Came to Dinner
The Ox-Bow Incident

Dr. Strangelove
Cool Hand Luke
Yellow Submarine
Easy Rider
True Grit
Terminator 1 and 2
A Clockwork Orange
The Martian
Lifeforce (there was some memorable nudity, though) A.I.
Boogie Nights (You have to go down to the tertiary characters like Buck and his wife, and the movie just isn’t about them) Never Cry Wolf
I know you said you maybe don’t remember much about the movie, but I’d sure like to see whatever plot summary — however brief — comes to mind.
Why, as per the title, does the prosecution’s star witness wind up testifying about the letter she addressed to “My Beloved Max”? (Does she, after stepping down from the witness stand, explain that she testified the way she did because of a man she loves?) Why did the victim, an older woman who’d been reading about older women who married younger men, leave all that money to the younger man who then winds up on trial for her murder? Can you explain the ending without making reference to “A Clinging Brunette”?
As I said, I haven’t seen some of these movies in a long time, but wasn’t the entire testimony by the star witness a lie, including the letter, which was a forgery? In fact, even the identity of the witness was a lie. I guess it’s the case that the real person who masqueraded as the star witness was motivated by love.
Do you really think Tin Man had a romantic attraction to Dorothy? At the end of the movie, the Cowardly Lion said, “Stay with us, then, Dorothy. We all love you. We don’t want you to go.” Does that mean he wanted a polyamorous relationship?
