Throw Momma from the Train is a 1987 American crime black comedy film starring and directed by Danny DeVito in his theatrical directorial debut.

It co-stars Billy Crystal, Anne Ramsey, Rob Reiner, Branford Marsalis, Kim Greist and Kate Mulgrew.

Novelist Larry Donner struggles with writer's block due to his resentment towards his ex-wife Margaret, who took all the credit for his manuscript and received acclaim for it, while Larry, struggling to make ends meet, takes a job teaching creative writing at a community college.

Owen fantasizes about killing his mother but can't summon the courage to bring his desires to fruition.

Owen tracks Margaret to Hawaii and follows her onto a cruise ship she is taking to her book signing, where he plans to push her overboard.

After having spent the night drinking alone on a beach during the hours of Margaret's disappearance, Larry panics because he lacks a sufficient alibi.

She is grateful to her son for saving her, but unappreciative of Larry's help and kicks him, resulting in him losing his balance and falling off the train to the tracks below.

During his recovery in the hospital, Larry discovers that Margaret is still alive; she had fallen overboard accidentally and was rescued by a Polynesian fisherman whom she has decided to marry.

Owen visits and informs him that his mother has died (albeit naturally) and that he's going to New York City for the release of his own book.

Farley Granger and Robert Walker appear via archive footage from Strangers on a Train as Guy Haines and Bruno Anthony, respectively.
