Even though Stan Lee may have passed away last year his memory is still living on thanks to his last cameo in Avengers: Endgame and Marvel Studios also hopes to honor his memory by creating a behind-the-scenes documentary of all of Lee's cameos!
Ever since the first X-Men movie in 2000, Lee has made a cameo in EVERY Marvel movie in one way or another and in a recent interview Marvel Studios President Kevin Feige confirmed that all the behind-the-scenes footage of Stan Lee being on set for his cameos will be compiled and released with a future Marvel movie's home release.
The footage also includes several deleted scenes that never made it into Marvel films! It's probably safe to assume Marvel would include it with the home release of either Avengers: Endgame, since that will be his last cameo, or Spider-Man: Far From Home just because of his ties to the iconic character.
You can check out Lee's final cameo in Avengers: Endgame, which is in theaters starting April 26th, but in the meantime you can see EVERY Stan Lee cameo to ever exist below!
