The Honey Pot (1967)

Rex Harrison hires actor Cliff Robertson to play a prank by inviting three former lovers (Edie Adams, Susan Hayward, and Capucine) to his supposed death bed. When one of the women dies, the investigation reveals more complicity and secrets. It’s a bit uneven in tone switching from outright comedy to murder mystery on the turn of a dime. It’s still quite a bit of fun for anyone who can appreciate such a mashup with quite an appealing cast that also includes a young Maggie Smith as Hayward’s dutiful nurse.
