The Yellowjackets actress—who starred in the family comedy fantasy film when she was 13—recently opened up about some regrets she has with how she played her character, Kat, who befriends the titular friendly ghost. “If you actually watch Casper, I’m horrible in it,” Ricci, now 42, said in an episode of the WTF with Marc Maron podcast on Monday, according to E! News. “People get so upset when I say that.” “I’m like, ‘No, it’s a wonderful movie,’” Ricci stressed, noting that “it’s a childhood treasure for people.” “But I am terrible in it,” she maintained. “There was a lot going on. I was 13. Everything was very difficult and I was just always annoyed.” “Embarrassingly… I don’t think I tried as hard as maybe I should have,” she added. Ricci—who is currently up for an Emmy for her role as Misty Quigley in Yellowjackets—said she was able to analyze her teenage performance in Casper from an adult perspective when she showed the flick to her 8-year-old son, Freddie, who she shares with ex-husband James Heerdegen. “I remember just thinking like, ‘Wow, that was not a good, no, not a believable line reading at all,’” she recalled. “No commitment. Not a lot of commitment.” Despite Ricci’s harsh criticism of her own acting performance in the classic family movie—which also starred Devon Sawa in the title role—the film still brought in more than $100 million domestically, per E! News. Other than Casper, Ricci also made a name for herself with her performance as Wednesday Addams in The Addams Family movie and its sequel, Addams Family Values. Ricci is also expected to appear in the new Netflix series Wednesday, although her role has not yet been announced. The series, which is from the imagination of filmmaker Tim Burton, is scheduled to premiere on Netflix this fall.
