This Is Us [1] season four is slowly coming together. NBC recently announced that the upcoming season will premiere in September [2], and the stars have already been teasing what's to come [3]. In addition to getting more answers about that cliffhanger in the season three finale [4], we're also going to meet a few new characters. Once Upon a Time actress Jennifer Morrison just joined the cast in a mysterious role [5], and we're sure more new additions will follow as the show casts actors for the flash-forward [6]. We've already met adult Tess [7], but we're definitely interested to see who will play adult Annie and adult Deja. Here are all the new and returning stars for This Is Us season four.
Mandy Moore as Rebecca
Moore will return as the Pearson family matriarch in season four.
