Even if you only know of the Marvel superheroes from their feature film adaptations, chances are you’ve heard of Stan Lee, the man who today is most famously associated with creating Spider-Man, the X-Men, Iron Man, the Hulk, Thor, and the Fantastic Four — along with iconic artists Jack Kirby and Steve Ditko. My colleague Darren Franich recently wrote about the sensitive nature of Lee’s claims of authorship — Lee himself has been careful of late to note he collaborated with Kirby and Ditko on those characters — but one thing is most certain: Few people have been better at telling their own story than Stan the Man.

Now 88 years old, he’s the subject of the documentary With Great Power: The Stan Lee Story, which will be playing at the Slamdance Film Festival in Park City, Utah, on Jan. 24. The film covers Lee’s life, starting from his Depression-era childhood, and features interviews with Tobey Maguire, Kirsten Dunst, Patrick Stewart, Samuel L. Jackson, Nicolas Cage, and Jon Favreau. You can check out the exclusive trailer below:
