The performances were great all around with good direction and a few really excellent scene compositions. I thought Jeffrey Wright, who played Belize/Mr. Lies, delivered the best performance. He was also the only actor carried over from the original stage production.
The real strength of this film is the fantastic writing. Tony Kushner adapted his own play and kept it largely unchanged. The ideas, the characterization, the dialogue, the plot, the imagery, the use of a kind of distorted magical realism; it's really great writing. Check it out if you get a chance, it's worth seeing.
