Ben Affleck as Matt Murdock cameo would have been EPIC
Since they had no problem bringing back Willem Dafoe and Alfred Molina from early 2000s superhero films, why not Affleck as Murdock INSTEAD of Charlie Cox? NOBODY would have seen THAT coming!
Everyone is talking about Charlie Cox's cameo and I was like "meh, so what?". He JUST played him in a recent MCU TV series. We already know the MCU TV shows and movies are always connected and characters crossover from the TV shows to the movies and vice versa all the time. Big whoop.
Affleck's return to the role would have been much cooler. And since the film's plot revolves around the multiverse, they could have certainly done it without it feeling forced. Peter Parker goes to see Matt Murdock for legal advise and Affleck's version of Murdock gets sucked into the MCU, goes to "his" old law office, and doesn't realize he's in another universe and can't figure out why Charlie Cox's portrait is on the wall.
That WOULD have been fun!
