Last night, Marvel invited fans to watch a special 15-minute IMAX preview of their highly-anticipated Phase Three adventure Doctor Strange. Part of this footage included the new Stan Lee cameo, and while it remains unclear if we'll get to see these scenes at all before the November 4 release date, new details about this cameo have been unveiled. There may be potential SPOILERS below, so read on at your own risk. attended the sneak preview last night, part of which showed an "epic foot chase" with Doctor Strange (Benedict Cumberbatch) and Baron Mordo (Chiwetel Ejiofor). During this chase, they collide into a bus, which is where we see Stan Lee. Here's a description of the scene below.

"In what looks like one of the most epic foot chases in cinematic history, Doctor Strange and Mordo are running down streets, up building sides, and across the sky as the world warps around them. After Kaecilius bends the building on which Mordo and Strange are running, they fall to the ground and into the side of a bus. As they fall, the camera angle switches to a point of view from inside the bus, revealing Stan Lee reading Aldous Huxley's The Doors of Perception. As Strange and Mordo smash into the bus' window, Lee bursts out saying, 'Now, that's hilarious!' until the camera swaps again and the chase continues."

Stan Lee's cameos have become some of the most anticipated moments in recent Marvel movies. He played a strip club DJ in 20th Century Fox's Marvel blockbuster Deadpool, and a FedEx delivery man in Captain America: Civil War earlier this year. We have plenty more cameos to look forward to as well, with the Marvel Comics legend cranking them out at a torrid pace.

Last month, Kevin Feige revealed in a Q&A session that Stan Lee's cameos are never random, and that he recently shot four cameos over one day in Atlanta for "various projects," with the producer stating that the cameos are all "awesome" and "totally different". In related Doctor Strange news, we also have a new TV spot for this superhero adventure, which arrives in theaters November 4. Take a look at this new footage below, as we get ready for the Sorcerer Supreme to hit theaters.
