from another scene. "Here's your chance to become a fumnambulist." "A what?" "a fumnambulist. Surely you know what it is?" "Yeah, it means some kind of idiot!"
Psssst.....I think it is spelled "funambulist," unless the word was purposely mispronounced for the movie.
The movie was "BACK DOOR TO HELL" starring Jack Nicholson. Try this one... "Have you ever done anything like this before?" "Now that you mention it, no." "Wonderful. Well you look real spiffy in the uniform"
"Hanover Street" It is. Hyams writes very funny dialogue. So, you guessed it in one. That's why you're the king! Your turn, your highness.
So... If it was indeed Mr. Marvin... Try this one... "Don't you like women?" "Yes indeed sir, but there's a time and place for everything"
