After wowing us as Wednesday Addams, Ricci starred in the sweet and ever-so-slightly spooky film Casper. Ricci's Kat moves into a haunted house that is already occupied by Casper, the most adorable ghost in the world. Their friendship anchors the movie, and it also led to quite a few people crushing on Casper in his human form, as played by Devon Sawa, thanks to their romantic dance at the end.
