Margot Robbie to Step into FOCUS with Will Smith July 16, 2013 Actress to star opposite Smith. Australian actress Margot Robbie (‘The Wolf of Wall Street,’ ‘Pam Am’) is reportedly the top choice to replace Kristen Stewart as the female lead in the long-gesting grifter movie ‘Focus.’ With Will Smith in the male lead, the story follows seasoned con artist who teams up with an inexperienced female. Robbie, who will next be seen starring in the Richard Curtis-directed sci-fi romance ‘About Time,’ is believed to have beat out the likes of Jessica Biel (‘Hitchcock’) and fellow Aussie Rose Byrne (‘I Give it A Year’) for the part. ‘Crazy. Stupid. Love’ writes/directors Glenn Ficarra and John Requa are behind the camera.
