The first Deadpool movie’s only major cameos were Stan Lee and Rob Liefeld, the former of whom has popped up in nearly every Marvel-related movie and the latter of whom was definitely deserving of a quick appearance since he co-created Wade Wilson.
Superhero movies inserting secret cameos is nothing new, but as far as Deadpool 2 is concerned, I’m particularly intrigued as to who the sequel brought in this late in the game.
I would imagine that neither of these two men returning for Deadpool 2 would warrant being kept a closely-guarded secret, so for now, let the guessing of this individual’s identity commence!
