Marking the launch of Turner Classic Movies HD at channel 317 on Sky on September 4, the channel will show three weeks of some of the greatest movies of all time.
This includes a first week featuring masterpieces such as Ben Hur, Cat on a Hot Tin Roof, Casablanca and The Philadelphia Story, all shown in HD.
From September 10, the channel will launch 'HD Western Week', involving films such as The Searchers, How the West Was Won and Rio Bravo.
That will be followed by 'HD Musicals Week' from September 17, showcasing favourites including The King and I, The Wizard of Oz and Willy Wonka and the Chocolate Factory.

"It's fantastic news that viewers now have the opportunity to watch TCM's vast library of great classic and contemporary films in HD-quality format," said Jemma Yates, the director of general entertainment UK and Ireland at Turner Broadcasting.
"This is another exciting step in the channel's continuing evolution, giving TCM's loyal and growing audience access to an outstanding viewing experience."
TCM has had a strong year in 2012, as month-on-month growth helped the network climb to become the third most-watched film network in the UK, behind Film4 and Sky Movies Premiere.
The channel has moved up from being the eighth most popular film channel in 2010 and now attracts four million viewers every month.
