Here's one for dialogue referencing other movies... this really captures the reality of a bunch of wastoids talking to each other through quotes...

NIL BY MOUTH (1997) written and directed by Gary Oldman

referencing APOCALYPSE NOW (1979) directed by Francis Coppola, screenplay by John Milius, Francis Coppola, and Michael Herr, based on the novel HEART OF DARKNESS by Joseph Conrad

"...his soul is mad. Oh, yeah. He's dying, I think. He hates all this. He hates it! But the man's a...He reads poetry out loud, all right. And a voice...he likes you because you're still alive. He's got plans for you. No, I'm not gonna help you. You're gonna help him, man. You're gonna help him. I mean, what are they gonna say when he's gone? 'Cause he dies when it dies, when it dies, he dies! What are they gonna say about him? He was a kind man? He was a wise man? He had plans? He had wisdom? Bullshit, man! And am I gonna be the one that's gonna set them straight? Look at me! Look at me! Wrong! You!"

Another one for movies mentioned in movies: Sleepless in Seattle where Sam (Tom Hanks) and Greg (Victor Garber) do their schtick about "The Dirty Dozen."

Another: "Casablanca" is all over the movie "Play It Again Sam."

Another movie in a movie is the mentioning of Wall Street in Boiler Room. The whole "reciting the lines" party scene.

How about philosophical comments?

"Do what you love and fuck the rest."
--Duane, "Litte Miss Sunshine"

SCOTT. u said major filmstudio read script from agency only.
THEN HOW WE CAN BE A MEMBER OF WRITER AGENCY??

@toomity: I already posted the answer to your question. You need to query managers and agencies to read your script. Before you do anything, make sure your script is in shape to be submitted to professionals. You have one chance to make an impression.

Death could be a cool theme, pref dying scenes.

I like all the suggestions but movies referencing movies could almost be a weekly feature.

- Back to the Future Marty referencing Star Trek and Star Wars.

- You've Got Mail, referencing The Godfather "go to the mattresses".

- Hot Fuzz referencing Bad Boys and Point Break (and others)

- Toy Story 3 references My Neighbor Totoro

- Star Wars also referenced in everything, including Bill and Ted's Excellent Adventure.
