Legendary Marvel Comics creator and publisher Stan Lee turned 95 on Thursday, and the stars of popular Marvel movies and TV shows, such as “The Avengers,” wished him a happy birthday on social media.

Mark Ruffalo, who plays the Hulk in the “Avengers” franchise, called the man who co-created Spider-Man, X-Men, Iron Man, the Hulk, Black Panther and others “the legend.” Chris Evans of “Captain America” fame and Don Cheadle (War Machine) also chimed in with birthday cheer.
