Rooney Mara

Actress and animal rights activist, Rooney Mara, achieved her career breakthrough with her role in The Girl with the Dragon Tattoo. Since then, she has gone on to act in other films, such as The Social Network and is continually working as a philanthropist. 

However, big money awaits Mara as her family has roots in the NFL lore. Her father’s family founded the New York Giants, with her father John owning half the team. Her mother’s family founded the Pittsburgh Steelers. We all know how much money there is in football, but if we are pretty certain it’s in the billions.  Yes, “billion.”
