The film's inaccurate portrayal of Prince Felix Yusupov and his wife Princess Irina ( renamed "Prince Chegodieff" and "Princess Natasha" ) resulted in a historically significant lawsuit against MGM and gave rise to the "all persons fictitious disclaimer" , which has since become standard in Hollywood works of fiction .
