We have a standard setup for a movie: Woman discovers husband has been unfaithful and her life is torn asunder. In this one, our heroine hits the road with her drunken grandmother. Chaos ensues.

Actually, we see a deft touch with this screenplay: real-life couple Ben Falcone and Melissa McCarthy co-wrote this R-rated script (language and sexual innuendos); as a result, it has far more going for it than I expected.

Directed by Ben Falcone, we see a star-studded cast:

• * Melissa McCarthy("The Heat") Tammy is a mess. She doesn't like her job and her "exit interview" is the most raucous and destructive I've ever seen. Her relationship with both her mother and her grandmother is "testy" to say the least and her husband just dodges her verbal barrages.
• * Allison Janney ("Bad Words") Deb despairs of her daughter ever completing anything she starts, including her marriage.
• * Susan Sarandon ("The Big Wedding") Pearl had always been closer to her granddaughter than Deb, but her parenting still left a lot to be desired. However, she still has a good eye for a guy!
• * Kathy Bates ("Harry's Law") and Sandra Oh ("Grey's Anatomy") Lenore and Suzanne provide our two runaways with a palatial shelter and a doozy of a party, which includes a Viking funeral for a jet ski (you'll just have to see it).
• * Toni Colette ("Lucky Them") and Nat Faxon (Lots of TV) are Tammy's heart-breakers. Missi is caught red-handed at Tammy's house with the faithless Greg.
• * Gary Cole ("Veep") My favorite chameleon plays Earl, a frisky old coot who will never see sixty again, as he brings a lot of action to the back seat of a Cadillac!
• * Mark Duplass ("The Mindy Project") Bobby thinks Tammy isn't the most un-interesting person he has ever met (read it twice - it doesn't improve....).
• * Dan Aykroyd (Lots of TV) Don has been a pretty absent father in Tammy's life, but he's willing to step up to the plate now!

This started out as a throwaway plot, but I think ACOA (Adult Children of Alcoholics) will embrace this as a pretty good example of the effects of alcoholism on a grown child. Be prepared for anatomical humor, vehicular mayhem, profanity and many laugh-out-loud moments. McCarthy is fearless! Based on the line for the screening, I think this gal can open a movie by herself!
