The latest is from Mandy Moore, who plays Rebecca Pearson on the series. Due to the many time jumps in This Is Us, Moore has often played her character in her mid-60's, which requires a bit of time in the makeup chair (given that Moore herself is only 38 years old).
In her latest Instagram Story, Moore revealed that she was transforming into the older version of Rebecca for the final time. The actress posted a video of herself getting makeup, which she captioned, “Last day with this gal forever!!”
