"Thanks for everything, Stan," wrote Ryan Reynolds, the star of Marvel's "Deadpool" movie series.

Comic book legend Stan Lee died on Monday and celebrities who have portrayed his Marvel Universe characters in movies and on TV are posting emotional tributes to his life.

Lee, who died at the age of 95, helped create some of the best-known comic book characters of all time, including Spider-Man, Hulk, Thor, the X-Men, the Fantastic Four and Daredevil.
