Meet the Star-Studded Cast of Life Itself, aka This Is Us The Movie

Olivia Wilde (who will always be known for her role as Thirteen on House) plays Mary, who is one half of the couple that the film revolves around. From the teaser, we see that she is very pregnant . . . just like Rebecca in the pilot of This Is Us. Will she encounter something similar to Rebecca's tragic and complicated fate? We'll just have to wait and see.
