4. Dick Van Dyke has a cameo.
Van Dyke played two roles in the original “Mary Poppins”: Bert and Mr. Dawes Sr., the elderly director of Fidelity Fiduciary Bank, where Jane and Michael’s father worked. He looks pretty unrecognizable in a fake wig, beard and old-age makeup.
Now he’s back playing Mr. Dawes Jr., but considerably less makeup was needed this time around. At one point, he jokes he still has “a few steps in me” – a callback to his big “Step in Time” number – and busts a move. At 92, he’s still got it.
