All right. This one is tremendously difficult.
Mainly because the movie was crap and nobody liked it, except me of course...

Hint A: "The library is closed. All white people must leave"
Hint B: "What difference does it make? What difference does it make?"
Hint C: "You're all doomed"

The right answer is:
This is the crap movie Hysterical from the year 1983

The geniuses that had the right answere were:

• Zelig:
"Júmm, myndin var slöpp og með leikara innanborðs eins og járnkjaftinn
Richard Kiel og Disney karlinn Keenan Wynn, það segir allt. En ég hló nú
samt eitthvað enda í upphafi unglingsáranna."
• Jack Nicholson:
"This is the movie Hysterical, and I say this in the firm belief that you will not post this on your page. I simply love this movie. The only movie I have watched over tvo hundred times."

A bank, a clown and New York...

"Let's see Miss Meryl Streep try to vomit on cue, huh?"

Svarið er:
Þetta er auðvitað stórmyndin Quick Change frá árinu 1990

Þeir sem sendu mér póst og vissu rétt svar voru:

• Zelig:
Quick Change er myndin með Randy Quaid, Bill Murray og Geenu Davis.
• Jack Nicholson:
Let me correct you on a couple of things here.
I have not only seen Meryl Streep vomit on cue, I've seen her nose bleed. A pity really, because they decided not to include that scene. However, I like Bill, and the movie is Quick Change. I was actually offered the role of Loomis but I was busy.
• Nohrs Ferratu:
Quick Change would be the correct answer to this question my dear
