#37: Kelly McGillis and Tom Cruise
It’s tough to picture Top Gun without the iconic mid-argument kiss between Tom Cruise and Kelly McGillis, but that memorable moment almost didn’t happen. The kiss only came about because Cruise, known for his professionalism, forgot his lines during the scene. Quick on his feet, he improvised by leaning in to kiss McGillis, hoping to cover up the slip.

The impromptu kiss worked perfectly, adding a spontaneous spark to the scene that resonated with audiences. The movie went on to become a massive hit and remains iconic today. While the film’s success wasn’t solely because of that unscripted kiss, it certainly added to its memorable charm.
