A Stan Lee cameo has become a secondary source of intrigue in Marvel Comics-based films -- when will he show up, what will he be doing and how will fit in with everything else going on? He's able to dwell in the worlds of the in-house Marvel Studios movies, Sony's Spider-Man films and 20th Century Fox's Fantastic Four and X-Men franchises. There have even been fan theories about how he can show up in so many different places.

The UK-based MorphCostumes, who offer a wide variety of skintight superhero bodysuits, have put together an infographic documenting Stan Lee's cameos in Marvel films, dating back to 1989's made-for-TV "The Trial of Incredible Hulk" and finishing with "Avengers: Age of Ultron," released this past May. This follows an earlier infographic from MorphCostumes, looking at the "Murderers of Marvel."
