A missed opportunity
The film studio guys must be kicking themselves for not bringing this idea to life. Imagine how many minds they could’ve blown if they had just cast Stan Lee as old-man Captain America. Each of his cameo appearances would have actually served a purpose!

Every time you see him in a Marvel film, it’s because he’s just checking up on his good buddies. That would have definitely been the best closure that they could’ve offered the late, great comic book creator. Thank you, Mr. Stan Lee, for everything you’ve given to the world. You are and forever will be sorely missed.
