Since the Oscars began, Casey Affleck has been sitting there suffering in mute silence, beginning with his being forced to endure the cruel japes of Jimmy Kimmel as he reminded Affleck he was only allowed to star in Manchester By The Sea because Matt Damon let him. As if that weren’t humiliating enough, when Kimmel cracked on Damon’s “Chinese ponytail” movie, Damon reached up and yanked on Affleck’s little man bun for the cameras. Then, as Kimmel did his big stunt of bringing a bunch of surprised tourists through the Dolby Theatre, he made a point of acknowledging that they probably wouldn’t even know who Affleck is. During his “Mean Tweets” segment, Affleck had to read somebody saying that he’s “the real-life version of Billy Bob Thornton’s character in Sling Blade.”
