Years ago I watched Leni Riefenstahl's, Triumph of the Will, on TV over Christmas. Admittedly, it wouldn't be to everyone's taste but does TV no longer do 'weighty' at Christmas?
they showed it again at 2am but no future dates given so the only way to see it now seems to be is either online or iPlayer http://www.bbc.co.uk/programmes/b04w815s
