Popsugar Entertainment Lonnie Chavis This Is Us Cast With Younger Selves Pictures The Cast of This Is Us Really Does Look Like Their "Younger Selves," and We Have Proof 20 March 2018 by Karenna Meredith A post shared by Iantha Richardson (@ianthasherii) on Mar 14, 2018 at 8:35am PDT Image Source: Getty / Kevin Mazur Ever since the very first episode, This Is Us has been throwing curve balls at us with different timelines and cast members. It's not everyday that you get to see a family "grow up" on screen and piece together how they became who they are. In order to pull off this emotional feat, however, the show cast multiple actors to play the show's leads at different age stages, including The Big Three (Kevin, Kate, and Randall Pearson) and most recently, Tess Pearson. While the cast may not appear on screen with their "younger selves," they definitely still have fun together behind the scenes and act like one big, happy family.
