Jennifer Grey & Patrick Swayze – Dirty Dancing (1987)

Patrick Swayze and Jennifer Grey were headed for disaster after their friction on the set of Red Dawn. And sure enough, while filming Dirty Dancing, the two were far from comfy with each other. Highly emotional and often crying at the slightest criticism, Grey made filming a nightmare for Swayze who complained that the actress would prolong many a shoot due to her inane silliness at times. Seems hard to believe given the magic this pair made on screen. They did end up friends, though far from lovers.
