Despite winning an Oscar at a young age, Anna Paquin admitted to David Letterman in 2009 that she had only recently watched the film for the first time at the time of the interview. She was not allowed to watch the film at the time of its release because of its sexual content being 11 years old at the time.
The play performed in the movie is an adaptation of "Bluebeard", which is a French fairy tale recorded by Charles Perrault about a man who marries, kills his wives after they fail a test, stashes their bodies in a small chamber, then marries again. In the original story, the main character (Bluebeard's current wife) escapes her psychopathic husband and finds happiness elsewhere.
The two similarly titled films, The Piano (1993) and The Pianist (2002), made and released around a decade apart, both won the same number of Academy Awards, that being three. All the Oscar winners for The Piano (1993) were women whilst all the Oscar winners for The Pianist (2002) were men.
Film debut of Anna Paquin. At the age of 9, she beat out 5,000 other girls who sent in audition videotapes for the role of Flora. (NOTE: Castle in the Sky (1986) is Anna Paquin's earliest listed role on IMDB. However, this was an English dub of a Japanese animation film by Hayao Miyazaki. Although the movie itself was first released in Japan in 1986, Paquin did not do the English voice-over for it until 1998. The Piano (1993) was her first film role ever.)
On-screen mother and daughter Holly Hunter and Anna Paquin have both appeared in superhero films with Hunter playing Senator June Finch in Batman v Superman: Dawn of Justice (2016) and Paquin playing Marie / Rogue in the X-Men franchise.
