Throw Momma from the Train

Writing teacher Larry Donner (Crystal) and his student Owen Lift (DeVito) have a lot in common: the women in their lives are driving them mad! Larry's ex-wife Margaret (Mulgrew) stole his novel and made it her own bestseller, and Owen's mother (Ramsey) is a monster! But Owen has a plan to kill both problems literally! He'll murder Margaret while Larry sends Momma to her maker! But when Owen fulfills his end of the deal before telling his teacher, Larry's left with no alibi and an outrageous obligation to knock off the nastiest old lady he's ever met!
