Repeat Performance (1947)

Sheila kills her husband at the start of the film with a smoking gun. We don't know how or why. All we know is men are banging on her door and she escapes. There is a notable dialogue as she makes her way to a New Years celebration with Richard Basehart as the poet William Williams. As she goes up the stairs to John Friday's apartment (her producer), she wishes she could relive the year and undo what she has done. William Williams, in an offhand remark, states he wishes he was the one who shot Barney, her erstwhile husband. We see that Destiny is not too happy with making changes to her plans.
