Greetings again from the darkness. Tracy Letts had a very nice year in 2008. He won the Pulitzer Prize and a Tony for writing the play August: Osage County. Since then, he has also written the play and screenplay for Killer Joe, and been seen as an actor in the key role of a Senator in the TV show "Homeland". This time out, he adapts his own play for director John Wells' (The Company Men, TV's "ER") screen version of August: Osage County.

With an ensemble cast matched by very few movies over the years, the screen version begins with what may be its best scene. Weston family patriarch and published poet Beverly (the always great Sam Shepard) is interviewing Johnna for a position as cook and housekeeper when they are interrupted in stunning fashion by Violet (Meryl Streep),Beverly's acid-tongued wife who is showing the effects of chemotherapy and her prescription drug addiction. This extraordinary pre-credits scene sets the stage for the entire movie, which unfortunately only approaches this high standard a couple more times.

Despite the film's flaws, there is no denying the "train-wreck" effect of not being able to look away from this most dysfunctional family. Most of this is due to the screen presence of a steady stream of talented actors: in addition to Streep and Shephard, we get their 3 daughters played by Julia Roberts (Barbara),Julianne Nicholson (Ivy) and Juliette Lewis (Karen); Ewan McGregor and Abigail Breslin as Roberts' husband and daughter; Margo Martindale (Violet's sister),her husband Chris Cooper (Charles) and their son Benedict Cumberbatch.

As with most dysfunctional family movies, there is a dinner table scene ... this one occurring after a funeral. The resentment and regret and anger on display over casseroles is staggering, especially the incisive and "truth-telling" Violet comments and the defensive replies from Barbara. As time goes on, family secrets and stories unfold culminating in a whopper near the end. This is really the polar opposite of a family support system.

Meryl Streep's performance is one of the most demonstrative of her career. Some may call it over the top, but I believe it's essential to the tone of the movie and the family interactions. Her exchanges with Julia Roberts define the monster mother and daughter in her image theme. They don't nitpick each other, it's more like inflicting gaping wounds. Surprisingly, Roberts mostly holds her own ... though that could be that the film borders on campy much of the time. Streep's scene comes as she recalls the most horrific childhood Christmas story you could ever want to hear.

It must be noted that Margo Martindale is the real highlight here. She has two extraordinary scenes ... each very different in style and substance ... and she nails them both. Without her character and talent, this film could have spun off into a major mess. The same could be said for Chris Cooper, who is really the moral center of the family. While the others seem intent on hiding from their past, he seems to make the best of his situation.

The film never really captures the conflicting environments of the old Weston homestead and the wide open plains of Oklahoma. The exception is a pretty cool post-funeral scene in a hayfield where Roberts tells Streep "There's no place to go". The main difference between the film version and stage version is the compressed time and the decision to include all explosive scenes. There is just little breathing room here. Still, it's one of the more entertaining and wild dysfunctional comedy-dramas that you will see on screen, and it's quite obvious this group of fine actors thoroughly enjoyed the ensemble experience.

It's Osage County, Oklahoma. Violet Weston (Meryl Streep) has quite a mouth and the mouth cancer to go with it. She's crass, addicted to painkillers, and the bitter matriarch of the dysfunctional family. Her youngest daughter Ivy (Julianne Nicholson) is still close by dutifully helping out but easily dismissed by Violet. Her sister Mattie Fae Aiken (Margo Martindale) keeps sticking around with her husband Charlie (Chris Cooper). Favorite oldest daughter Barbara (Julia Roberts) has returned with her separated husband Bill Fordham (Ewan McGregor) and daughter Jean (Abigail Breslin). Violet's husband Beverly (Sam Shepard) has enough of the her difficulties and walks off. He is found drowned and the family gathers for the funeral. The middle daughter Karen (Juliette Lewis) returns with new fiancé Steve Huberbrecht (Dermot Mulroney). Little Charles Aiken (Benedict Cumberbatch) is the loser son of Mattie Fae and Charlie who overslept for the funeral.

There are a lot of great actors doing Oscar caliber work. The best thing director John Wells does is to point the camera and let these actors work. Meryl Streep is the master, and there is no way to describe her work with justice. Julia Roberts kept up with her and that is high praise for any actor. Every person in the cast deliver some of their best work. Writer Tracy Letts' play is all the same tone. That is the movie's biggest drawback. It is all vile and all bitterness. It is the same tone over and over again. It is overkill without any letup. I just enjoyed it for the performances.

Granted, I wouldn't last five minutes with this bunch. But having grown up with people not unlike this, I found the parrying and thrusting to be quite real. These characters are all inflicted with the same disease; they need love and drill for it, but they are incapable of letting go of their submerged self-hatred and continue to bring each other down. If you can get past that, you can sit and watch the disaster happen and appreciate some really intense performances. Black comedy is not "funny" the way that farce or physical comedy are. Black comedy draws its strength from seeing our lives as absurd and unfulfilled and still going on. Sartre thought that we all had had a terrible joke pulled on us. If we live in this septic tank, bless us. If we can rise above it, bless us too. The dialogue is real, the awful failure to express love and respect is well presented, painful as it may be. While this was not a pleasant experience, I could not take my eyes off the principles. I think about this movie all the time which means it must have got to me.
