I was never much of a Burton fan, and while I think that Peter O'Toole's Henry II in "Lion in Winter" is better than his Henry II in "Beckett" I'll concede that "Beckett" is the more watchable movie of the two. Still, "Lion in Winter" has Hepburn, who's fantastic. And Paul Scofield's performance of Sir Thomas More is without peer.
All three of those are good winter afternoon films. They really dont make them like that anymore.
