Hot off-screen couples with zero on-screen chemistry
Over the weekend I watched the hot mess that is the direct-to-Hulu thriller Deep Water, starring exes Ben Affleck and Ana de Armas. This movie has all the ingredients to be sexy, from the hot leads to its source material (it's based off Patricia Highsmith's novel of the same name) to the fact that it's directed by none other than Adrian Lyne, who is known for making sexy thrillers like Fatal Attraction and Unfaithful.
The movie is a campy disaster and Affleck and de Armas have subzero chemistry in it. When I wasn't trying to piece together the inane plot, I spent most of the runtime wondering, "Wait, these two hooked up in real life?!" They both look incredible on screen here, but everything about them as an on-screen couple rang so incredibly false. Even their kisses were cringe-worthy. I can only chalk it up to these two saving all the good stuff for when the cameras stopped rolling.
Of course, Affleck is no stranger to this, as he and one-time ex J.Lo made the famously awful Gigli. Similarly, they were great together for the paparazzi cameras and terrible when a director yelled "Action!"
Who are some of the other examples of hot (and, likely, doomed) couples who had terrible on-screen chemistry?
