Star Wars: The Empire Strikes Back
Here’s Harrison Ford with yet another improvisation. In Star Wars: The Empire Strikes Back, Hans Solo shares a tender scene with Leia before he was about to be frozen alive. Leia confesses, “I love you” and Solo replies, “I know.” This was actually all Ford’s doing—and it worked out great because of how well it fits the character.
Young Frankenstein
Next on the list is Young Frankenstein that also features Gene Wilder. But let’s forget about him this time and instead focus on Marty Feldman. He played Igor. Director Mel Brooks encouraged the cast members to improvise. That includes the famous “What hump?” line delivered perfectly by Feldman!
