Because I have an enormous weakness for “Mary Poppins,” Emma Thompson (particularly when she dismissively says “cavorting and twinkling”), anything that makes me think about Julie Andrews, and the whispered phrase “Wind’s in the east, mist coming in /Like something’s brewing, about to begin” . . . here is the trailer for “Saving Mr. Banks.” I mean, look at this cast: Thompson, Tom Hanks, Colin Farrell, Paul Giamatti, Rachel Griffiths, Ruth Wilson . . . BJ Novak and Jason Schwartzman as the Sherman brothers. Can’t wait to see this one, but I’ll have to; it’s due in theaters around Christmas.
