"It was haunted, okay?" Plaza, who plays newly-wealthy married woman Harper Spiller, told E! News' Erin Lim Rhodes exclusively at The White Lotus' red carpet. "The monastery was haunted. The hotel was haunted. It was the ghosts. The Ghosts of Christmas Past, or whatever."
And while Plaza didn't own up to pulling the pranks, she did note that a few of her cast mates tried to take revenge—although they didn't succeed. After all, as she bragged, "People can't prank me."
So, how did all of these shenanigans begin? Plaza let the story slip on Aug. 18's episode of Jimmy Kimmel Live, describing how pulling a trick on one of her costars caused the hotel staff to track her movements over security cameras.
