Caddyshack, of course.
“I can’t help but notice that you seem a little at war with yourself here.”
I thought it might be too easy. Almost went with this one, “Don’t sell yourself short . . . . You’re a tremendous slouch.”
Although it is nice to get one someone guessed. I think I have a lot of unsolved quotes in this thread.
Another clue: The two actors played equally famous historical personalities.
You could have tried…
“That’s a peach, hon”
Or maybe
“Carl Lipbalm died last week”
Too obscure?
Final clue: The name of the movie coincidentally became that of an international megahit pop song in 1974.
Was there a movie version of Waterloo?
Well tanks fer nuttin.
Love that. I think I did it in this thread.

Anybody get this one?
“Could we not dye it red, at least?”

“White is for babies!”

IIRC, I saw it the spring I was finishing fifth grade (1966). I’ll give you some clues:
The main star was one of Hollywood’s most popular pretty boys. He was oddly paired with one of Hollywood’s biggest goofballs.
The movie focused loosely on the aviation industry.
The quoted line was spoken by a buxom German lass (obviously).
“Not …my… gentle son”
You have no idea the hell storm you fixin’ to let loose.
“You flatter me.”
“Oh, how clumsy of me. I meant to accuse you.”
