Director Rob Marshall's Mary Poppins Returns is a movie with a whole lot of whimsy and heart, featuring some great music and performances, but when I think back on the 2018 film, my brain immediately goes the brief role played by Dick Van Dyke. Having previously played Bert the chimney sweep and Mr. Dawes Sr. in the original Mary Poppins, the actor's appearance in the film is delightful in and of itself – but it's what he ends up doing in his turn that makes it one of the best cameos in recent memories, and it apparently had all of his castmates on set in tears.
