These On-Screen Kisses Were Actually Totally Unscripted
Top Gun – Maverick and Charlie

Top Gun is a classic film that is remembered for the iconic scene between Charlie (Kelly McGillis) and Maverick (Tom Cruise). In the scene, Charlie admits her feelings for Maverick but wants to keep them a secret, when suddenly he kisses her passionately.
Surprisingly, the kiss was not part of the script and was a result of Cruise forgetting his lines. To improvise, he decided to go for a kiss, and the director liked it so much that it made it into the final cut of the movie. And now, it remains one of the most memorable movie kisses of all time.
