They would never be able to do something like tropic thunder today.
As far as the "It's always sunny" episode...
FXX’s
It’s Always Sunny in Philadelphia is revisiting a past controversy in its current fifteenth season.
In 2020, Netflix pulled an episode of the long-running
comedy titled
Dee Reynolds: Shaping America’s Youth, which included an interpretation of
Lethal Weapon 5. In the episode, show creator and cast member Rob McElhenny plays Danny Glover’s character, Murtaugh, and uses
blackface. A later episode offers
Lethal Weapon 6, which also uses blackface.
But times change, and what was once deemed funny now is viewed differently in 2021.
McElhenney acknowleged that the show sometimes goes too far in remarks at an FX Network press conference.
So yeah, that episode kind of been 'cancelled'..
