10 Predictions For 2019 Movies That Everybody Got Wrong
2. Arthur Fleck Is Bruce Wayne's Half Brother - Joker
Much like the Far From Home marketing team strategically shaping their trailer to misinform the masses, and Star Wars pointing to a Rey heel turn that was never going to happen, those involved with Joker chose to share some key information that would lead theorists down the wrong path.
Before the movie's release, we found out several key details about Arthur's mother, Penny. She was at one point an attractive young woman, and was obsessed with Thomas Wayne whilst in his employ. These two pieces of information pointed fans in the direction of believing Arthur Fleck would be the half brother of Bruce Wayne.
And for a while, those who pieced this together must have been feeling pretty smug when Penny informed Arthur of this during the movie, seemingly confirming the theory. But it wasn't to be. The truth was later revealed that Mrs. Fleck often suffered from a delusional state, and had never had such a relationship with Mr. Wayne.
Though this would have been an interesting take on the relationship between the two would be brothers, the numbers just didn't quite add up. During the movie Arthur is firmly sat in middle age, while Bruce is merely a child.
