Zegler Effect

When someone playing a character acts so despicably, is so hated by their potential audience, that they damage the project they are in beyond repair and cause the studio they work for to lose money by making the general public actively root for it to do poorly.

Popularized in the slew of videos offering play-by-play coverage of Disney's Snow White remake, where Rachel Zegler's behavior during interviews, on social media, and even on-set, have torpedoed the film's chances of doing well.

"The Acolyte wasn't very popular to begin with, but then the Zegler Effect kicked in when the lead actress dropped a diss track mocking her critics."
