Arsenic and Old Lace
Hamlet
Romeo and Juliet (cliche, but I love it!)
Pygmalion

Screenplay-wise, my favorite would be Richard LaGravanese's "The Fisher King." Followed by Anthony Minghella's script for "The Talented Mr. Ripley." (Although I also loved the original screenplay for the movie "Arthur," which reveals a really surprising hint of sadness and soul that haunts the movie's funny sweet edges.)

Play-wise, my favorites (and there are so freaking many!) would include Lettice & Lovage (Peter Schaeffer), Christopher Durang's "Laughing Wild," Arthur Miller's "The Crucible," Wendy Wasserstein's "The Heidi Chronicles," and the lovely book to "The Fantasticks."

Another great one here: Proof.

I love the story and the rhythms of this script. It flows really nicely.

I heard that David Auburn's other stuff isn't up to par, though... even the style and rhythms are odd. Anyone read his other stuff? Have any opinions?

Although they could be TOO smart for their own good, anything written by THE COHEN BROTHERS.

I LOVE MILLER'S CROSSING, RAISING ARIZONA and O'BROTHER WHERE ART THOU.

Ok I gotta give myself props so what the hell:
two of my scripts that were produced:

SOUTH BRONX 10467-A play within a play that spoofed "Beverly Hills 90210" in the hood.

and
SURRENDER-great freaking script that I have to outdo. Go to youtube to see a clip.

DOUBT by John Patrick Shanley

WOW.

I read the play and found it STUNNING in its drama. Mind blowing in drama. The CONFLICT is intense. And the POINTS OF VIEW OF EVERYONE are UNDERSTANDABLE.

It's an astonishing play. When I read it, and I got to the last line in the play, I literally gasped.

It's ASTONISHING. (And I've never seen the play, only read it.)

Mark my words: I WILL play Father Flynn. If I have to mount the production myself, I WILL play that part. That's a dream role.

ALL MY SONS by Arthur Miller

My favorite American play. What a DRAMA. What CONFLICT. What POINTS OF VIEW. This is one intense night of theatre.

CASINO.

The Scorsese movie.

The wildest ride. DeNiro and Pesci. One of the great performances.

I love August Strindberg! "The Father", "The Stronger", both amazing plays. I also LOVE Noel Coward's "Private Lives". Oh, one of my all time favorite plays of all time, "Look Back In Anger" by John Osborne. I highly recommend this play if you've never read it. Sooo good. It's about a married couple, real sweet loving compassionate wife who is verbally abused by her husband through out the play. She ends up... well, I don't want to give it away, but it's very powerful

Movies, I totally agree with "The Dude's". Coen Brother fan all the way! But you forgot to mention FARGO!!! Lucia Y El Sexo, one of the best twisted scripts ever and BEAUTIFULLY executed! Another one I highly recommend!

Psychosis 4:48 - Sarah Kane. Genius.

I really loved watching Heights.Its a film with glenn close,james mardsen,elizabeth banks.Its sooooooooooo good.Its about these 3 or 4 intertwinig stories in nyc.Glenn close plays an acting teacher at juliard and world renowned classical actress.her husbands having an affair with someone close to her,her photographer daughter is getting married.meanwhile another aspect of the story is a racy photograph exhibition that is crucial to the plot......glenn close is the reason i am inspired to keep on acting.that woman is amaaaaaazing.here is the imdb link.
http://imdb.com/title/tt0382073/
also,i am addicted to "the opposite of sex"christina ricci,martin donovan,lisa kudrow etc.christina ricci narrates playing a small time whore,who is fully aware that she is above her friends,family and well sex. she makes false claims about her babys daddy and she moves in with her half gay brother and trys to sleep and run off with his bf. I love christina ricci and i love this movie beyond words.

Chain by Pearl Cleage...one of my dream roles...

who was the lead in chain?

I just re-read Lillian Hellman's The Little Foxes. Amazing play with some wonderful, meaty women's roles.

"Amadeus" is still a favorite -- Salieri is such a juicy part.

Also, recently read "How I Learned to Drive" and "Sideman." Different stories, but both have interesting characters -- good stuff to sink one's teeth into.

Coen Bros. fan's: don't forget "Miller's Crossing." An earlier film that is often overlooked. Albert Finney and Gabriel Byrne. Very solid.

The House of Blue Leaves
I Am My Own Wife
Women of Manhattan - some great comedic female roles

I'm sure there are others but I can never think of them on the spot!!

I love My Three Angels and A Company of Wayward Saints. Both are very funny!
