First of all, it really helps if an actor is keen to take on a role. Their enthusiasm in playing the character will translate into how they tackle it on-screen, and it provides fans with some reassurance that their favorite hero is in good hands – this is even more important in a Cinematic Universe where actors return to roles a number of times. Affleck’s uncertainty and apparent lack of dedication has turned some fans cold on his inclusion in these movies, so Hamm having this level of drive to become Batman is a great start.
Not once have other actors such as Henry Cavill and Gal Gadot, who play Superman and Wonder Woman respectively, had these same rumors surrounding them. This leaves us to think that it’s more than just a rumor whenever another report comes around saying Affleck’s days are numbered. So, when it’s revealed that “Jon knows Ben has faced some criticisms over Batman v Superman and Justice League” but still wants in on the franchise, then he must be serious about the role.
