Ok, it’s time to compare the facts.
1) Joker is famed for its portrayal of Arthur Fleck’s mental state. This is shown through a relationship he believes he is having with a woman through the audience perspective. A movie did this years earlier, a movie called ‘Fred: The Movie’.
Furthermore, there are portions of Joker where he is sad, looking though a bus window. Near the end of ‘Fred: The Movie’ the exact same scene happens.
Finally, I must point out that ‘Fred: The Movie’ came out in 2010, while Joker came out in 2019, 9 years later.
Conclusion: Joker (2019) is a direct ripoff of ‘Fred: The Movie’, and all the awards earned by Joker should go to ‘Fred: The Movie’.
