One of the actors from the original, Dick Van Dyke, will be making a cameo appearance, but the original Mary Poppins, Julie Andrews will not.
The sequel to Mary Poppins is currently filming and it will be here in 2018.
However, the truth is quite the opposite.
According to the director, Andrews is staying out of the film because she doesn’t want to do anything that might take away from Blunt portrayal of the magical nanny.
