In my recent exploration of classic cinema icons, I discovered that Charlie Chaplin and Buster Keaton, indeed, crossed paths. They were not just acquainted but also worked together in Chaplin's film "Limelight" in 1952. This was a significant moment, as it was the only time these two silent film legends shared the screen. Despite their professional rivalry, they had a mutual respect for each other's work. It's fascinating to contemplate the combined genius when these two met and collaborated.
