I realize that this is basically a tease of a tease, in that we don't see any actual footage of the film, but apparently a snippet was unveiled this weekend at the Disney Fan Club Expo (D23), and the audience freaked out.
Of course Meryl has a supporting role in the picture, playing Poppins's cousin, Topsy Turvey. The film opens nationwide on Christmas Day, 2018.
