I didn't mean actors, I meant characters. Most of that IP was grade A stuff. Thor, Iron man, Hulk, Captain America, Spiderman. They brought in some second tier characters as part of the Avengers stuff before broadening their case but you only have to look at a film like end game to see how much people value the characters. It was an OK film but people raved about it because it was the finale to this phase and had emotional endings for their favourite characters.
Like I said, who knows, it might go well but I'm not convinced at the moment. Disney has been placing too much value on the wrong things for a few years now in their films so we will have to see what happens.
