“Kate and I have been looking for something to do together for 20 years, since our collaboration on 'Titanic,' which was one of the most rewarding of my career,” Cameron said, according to Deadline Hollywood. “I can’t wait to see her bring the character of Ronal to life.”

Cameron and Winslet worked together on the 1997 epic film “Titanic.” The movie was the highest-grossing film of all time until “Avatar” surpassed it. Winslet was nominated for the Best Actress Oscar for her portrayal of Rose DeWitt Bukater in the film but lost to Helen Hunt. She won the coveted award in 2009 for “The Reader” after being nominated five times previously.
