Do you recall the scene, Jack, in "It's a Mad, Mad, Mad, Mad World" where David Niven and some American guy (can't remember who) drive each other slowly around the bend over a day or so and finally get into a hilarious fistfight out in the boondocks somewhere

Just about everyone else in the world was in that film except David Niven. Maybe you're thinking of Terry Thomas? Wasn't he stuck with Milton Berle? (Been a long time since I watched that one.)
