MARVEL: Ultimate Alliance fan-made video
Truthfully, if MARVEL had ALL their comicbook properties under their own brand/banner (or rather under Disney), then DC Comics would truly be quivering under their superhero boots, Justice League of otherwise, IMHO.
Here's my sketchery of a MARVEL cinematic trio, featuring two characters on the fringes of the supernatural that should not be forgotten, methinks! As for Doctor Strange, I've always been partial to the 2006-07 mini series "Doctor Strange: The Oath" written by Brian K. Vaughan, with art by Marcos Martin.
