are you perhaps thinking of Maj. Major Major from "
Catch-22 (1970)
"?
"I'll do the masterminding around here."
-Sgt. Stryker, "Sands of Iwo Jima"

in
Doctor Strange (2016)
. Dialogue goes like this:
Kaecilius: You'll die defending this world, Mister
Dr. Stephen Strange: Doctor!
Kaecilius: Mister Doctor?
Dr. Stephen Strange: It's Strange!
Kaecilius: Maybe, who am I to judge?
Not exactly what you wanted, but funny enough to include
"As quickly as you can snatch the pebble from my hand."
Honga-Hula!

There's a character on South Park named Dr. Doctor.

Yeah, that's not what I'm looking for but thank you very much.

There was a scene with that dialogue in Spies Like Us.?
