A few months later, it was reported that Affleck felt “humiliated” after spending so much time during the press tour saying that Batman v Superman would be better than his previous superhero outing, 2003’s Daredevil.
“Sound of Silence” just happened to be the most fitting track to lay over the footage.
The general idea behind the Sad Affleck video is because Batman v Superman: Dawn of Justice’s less-than-stellar reception hit him harder than most, hence why he looked so glum and only responded with “I agree” after Henry Cavill gave his response in that interview.
