Olivia Hussey wasn't legally allowed to watch a movie she starred in, because it had a nude scene. She was the one that was nude.
Olivia Hussey gained fame for her first starting role as Juliet in the 1968 film "Romeo and Juliet." The film, directed by Franco Zeffirelli was released to critical acclaim, winning Oscars for Cinematography and Costume Design, and receiving nominations for Best Director and Best Picture.
One of the things that made it the most successful Shakespeare movie ever at the time was that it was the first one to use actors that were close to the age of the original play's characters. Olivia Hussey was only 15 at the time!
When the movie premiered in London, Hussey was not allowed to attend, because the movie featured a nude actress… herself! The director had to get special permission to film her nude, but she still had to skip on the premiere.
Another interesting fact, the movie was originally rated G in the United States, but because of the nudity it was re-rated, to the incredibly more restricting PG rating.
