I really thought the “Mooska” would give it away:
Yes, that’s Madeline Kahn in her first film role.
“So when a half-breed breaks the rules, I deport their sorry ass straight back to hell.”
One more hint: He was an entertainer and an activist of sorts.
A: “Ah, Monsieur? Téléphone pour vous.”
B: “Téléphone? Pour moi?”

French waiter to James Coburn in The Great Escape
Coburn’s character, a just-escaped POW, knows that the telephone call can’t possibly be for him. The waiter, a member of the Resistance, is just trying to get Coburn out of the Line of Fire, because the German officers at the same sidewalk cafe are about to be gunned down.
The movie The Great Escape, while well-done and exciting and clearly done with the advice and cooperation of former POWs, nevertheless took amazing liberties. One was in giving Americans a much bigger role than they actually played in the escape (not their fault – the Germans separated them from the British early on) and the second was in being far more violent than reality. There’s no way the escapees would have done a lot of the things they’re shown doing in the film – there was too much risk of retribution.
All correct. 
Here is the scene:
I like the bell ringing in the background. Nice touch of impending doom!
Constantine
‘Didn’t we just leave this party?’
Damn! I know this line, but I can’t think of the movie!
I’m hearing all kinds of voices: Lee Marvin, Clint Eastwood. Mel Gibson, Bruce Willis…
Star Wars, of course. Princess Leia to Han Solo and company, running around the Death Star.
“So many guns around town, and so few brains.”
That’s it!!! 
Actually, it was Han saying it to Leia.
It was also regularly quoted by me to my co-worker Amanda at Blockbuster whenever we did a close/open together. Which happened a little too frequently for our liking.
‘The Big Sleep’?
Support Your Local Sheriff/Gunfighter?
You will get along beautiful in America.
Casablanca
“Perhaps I can find new ways to motivate them.”
Return of the Jedi. And I love that line.
Oh yes, me also.
“…you look very nice, you’re wearing your cocksucker.”
Meryl Streep as Sophie, to Peter MacNicol’s “Stingo.” Her Polish character meant “seersucker.” A gutwrenching scene.
“Go on out and get some air, fatso!”

Would the judges also give credit for this answer:
