So, we can say emphatically that the film Weekend at Bernie’s does not stink (from his corpse rotting, at least). Meaning the movie could have theoretically missed the smell window, or did not go on long enough for the smell to be noticed. However, there are still some minor issues with hauling around a dead body. Rigor mortis would have been at full stiff tilt within 12 hours, making madcap hijinks the next day highly unlikely. And after 4 hours, blood would pool giving him purplish skin, in fact, his hands would turn blue after 30 minutes, making it hard to pass Bernie off as a tan and happening party goer. Plus Bernie was submerged in water twice throughout the film, which would have made him a bloated, purple mess by the final scene.
And perhaps most importantly, Bernie would have released his bowels mere minutes after death. And remember Bernie was wearing the same outfit the entire time, the same soiled pants for an entire day. So, Bernie does smell, but like shit, not like death. There really needed to be a scene of Andrew McCarthy wiping Bernie’s ass with a wet nap, doing a load of laundry, or scrubbing away brown trails through the entire summer home.
