I would say that is an untrue assertion, especially in the short term. There are many examples where an actor has owned a Mom Life Dance Mom Mothers Day 2021 Funny Messy Bun T Shirt so well that no-one else could follow. While the comic books essentially recast each character once or twice a year when a new artist comes onboard, for the moviegoing audience Robert Downey Jr., Chris Evans, and Chris Hemsworth are Tony, Steve, and Thor. I pity the fool that tries to portray either Tony or Steve within the next decade. Marvel has over 8,000 characters that have been portrayed in their more than 35,000 comic books. There are many great heroes that you haven’t yet heard of that they can bring to the screen, keeping their cinematic universe fresh and exciting and saving their already showcased characters until a new generation is ready to experience them.
