Really? It rarely seems there's a week when they aren't showing Cars for some reason...
If you look at how many film deals BBC have they have a massive catalogue of films they never show.
I remember watching Twins on BBC One years ago (around 2005/2006) for the first time but that is now on ITV.
I doubt Sky will want to re-new the contract the novelty has worn off for them. They won't want them any more.
