Joaquin Phoenix, the actor who played Arthur Fleck in Joker, has been making quite the victory lap since the award season started. The critically acclaimed film portrays more than just a spinoff from a comic book. It has functioned as a portal that provides an accurate representation of the development of mental health issues as a result of a society that denigrates individuals and what it means to be human. Rightfully so, Phoenix has been gathering quite a bit of hardware, including the Golden Globe for Best Male Actor. More recently, though, Phoenix won the award for Best Actor at the Screen Actor's Guild and he thanked a well-known person as the inspiration for his character.
