CITY Screen, York, closes for only one day in the year – Christmas Day – and then reopens with a Boxing Day bonanza of new films, led by exclusive previews of Mandela: Long Walk To Freedom.

Idris Elba stars as the late South African freedom fighter and president with Naomie Harris as his volatile wife Winnie Mandela.

Veteran Robert Redford's tour-de-force All Is Lost, a demanding and near-silent drama of a man battling to save his crippled sailing boat and his own life, also opens as does Ben Stiller’s reworking of The Secret Life Of Walter Mitty, James Thurber’s short story about a meek, office-bound fantasist.

Director Stiller takes the title role, supported by Kristen Wiig and Sean Penn.
