They did bring back Dick van Dyke to reprise one of his roles from the 1964 movie. But NOT the chimney sweep character. Apparently he also played the elderly bank president and now he’s old enough to NOT need makeup for the role!
I always admired DVDyke from his role in the DVD show and Mary Poppins. Then I watched a one-man show of his where he put on display his true character. Based on that I now see him as an evil old man. His language was beyond atrocious.
