Weekend at Bernie's (1989)

In director Ted Ketchoff's summer sleeper hit black comedy:

• the memorable scenes involving the murdered corpse of boss Bernie Lomax (Terry Kiser) who was propped up to appear alive - pretending to be the host of a weekend beach party in the Hamptons over Labor Day weekend
• the scene of the two insurance company employees: slacker Larry (Andrew McCarthy) and uptight workalcoholic Richard's (Jonathan Silverman) speedboat departure that dragged Bernie's body into buoys
• the off-screen scene of the visit of NY moll Tina (Catherine Parks) to his bedroom for sex (without noticing his unresponsiveness)
