Emma Thompson is a crotchety hoot as PL Travers, the reclusive author who gave Walt Disney (Tom Hanks) a tough time in bringing her most precious creation - Mary Poppins - to the big screen.
After refusing to give up the rights for 20 years, Mrs Travers finally comes to Hollywood on the understanding that she will have approval over any adaptation. No singing. No animation. No Dick Van Dyke. So what would it take to make the medicine go down?
A true story as endearing and characterful as the classic it brought about.
