Actress Connie Nielsen has been cast to play Wonder Woman's mother Hippolyta in the 2017 Wonder Woman film, according to The Hollywood Reporter. Nielsen recently appeared in the television shows The Good Wife and The Following, but is perhaps best known as the queen Lucilla in 2000's Gladiator.
Interestingly, THR spells the character's name as 'Hippoyta' in the article, but in comic books the common spelling is 'Hippolyta.'
In comic books, Hippolyta is the ruler of the Amazons. For a time, she even worked under the moniker of Wonder Woman while Diana was away.
Wonder Woman is currently shooting in the UK and Italy, and is scheduled to be released June 23, 2017.
