This is the first five minutes or so of Stan Lee's panel at the 2014 C2E2. They only wanted us to take pictures or video for the first few minutes. But later on, during Q & A (not in the video), he was asked a couple intriguing questions that led to intriguing answers.
When asked why he shaved his mustache, he started answering with "I was doing some work on a hologram project..." and a guy came running up on stage to shut him up.
When asked if he has a cameo in Guardians of the Galaxy, "He started answering with "I do have a cameo with a beautiful woman..." and the same guy came running up on stage to shut him up.
Sorry I couldn't get those two things on video, but it wasn't allowed.
