I loved this play, too, and really found it interesting that script served both sets of actors on Broadway, Mercedes Ruhl and Bill Pullman/Sally Field and Bill Irwin. Saw both companies. Curiously, I thought Sally might've been better paired with Pullman however, and Irwin with Ruhl. The two women couldn't be more different, yet both made the wife's role distinctive and hysterically funny. When Fields exploded, it was the mouse roaring, whereas Ruhl found more "Martha" in the part, the braying, wounded dame. My only problem with the script was the somewhat sluggish beats with the best friend and the video equipment, not terribly well-played on Broadway.
