Despite buzzy awards season mentions, John Lee Hancock’s Saving Mr. Banks (C+) is a tepid, often dull melodrama about the clashes behind the making of Mary Poppins that would be more at home on Lifetime than the silver screen. Tom Hanks in cheerful mode as Disney and Emma Thompson as frigid writer Travers make the most of their stock roles, but a lethargic storyline punctuated by tedious flashbacks of the author’s tragic kingdom doesn’t add up to a spoonful of much.
