Film and television appearances

Lee had cameo appearances in many Marvel film and television projects, including those within the Marvel Cinematic Universe. A few of these appearances are self-aware and sometimes reference Lee's involvement in the creation of certain characters. He additionally voiced a cameo appearance as himself in the 2018 DC Comics movie Teen Titans Go! To the Movies. Out of respect for Lee, Marvel Studios enacted a new policy following his death that forbids cameos by Lee in new films by using archive footage of him, with Avengers: Endgame (2019) marking his final appearance; the film was released several months after his death.

Lee was featured with his colleagues and family in the 2010 documentary With Great Power: The Stan Lee Story, which explored his life, career, and creations. A special titled Stan Lee, chronicling the life and legacy of Lee, was released on June 16, 2023, on Disney+. It was directed by David Gelb and first premiered at the Tribeca Festival.
