“Stan Lee sat down with Breakfast Television for an interview during his time at Canada Fan Expo” – during his visit to Toronto – heroichollywood.com
During the (mentioned above) interview, Lee confirmed that he has completed filming for Doctor Strange, Guardians of the Galaxy Vol. 2 and Spider-Man: Homecoming.
Lee also added that he does not get a say in how big or small his roles are:
“Oh no no, they decide. If I was deciding it would be a half hour role. They only give me a few seconds, and they’re afraid, you know, I’ll overshadow the star. You know how that is.”
Lee has already amassed 30 cameos to date – most recent one appearing in Captain America: Civil War, where Lee appeared as a Fed Ex driver towards the end of the movie*.
