I Wonder Who's Killing Her Now?

I Wonder Who's Killing Her Now? (original USA theatrical name Kill My Wife, Please) is a 1975 black comedy movie directed by Steven Hilliard Stern, and starring Bob Dishy and Joanna Barnes. Originally Peter Sellers was to be cast as the lead but he had another heart attack and insurance couldn't be got on him so Dishy was his replacement at the last moment. It was directed by Steven Hilliard Stern, from a screenplay by Mickey Rose. The title is a play on the old musical I Wonder Who's Kissing Her Now. Soundtrack is Polonaise Op.53 in A flat major (Frédéric Chopin).
