Apparently Heath was being considered for a role in Crazy Heart

Thanks for that info, trekfan. From that article, "But there was a scene that Cooper shot with Bridges and a local Texas actor in the part that was to have gone to
Ledger. Despite, or perhaps because of, that chilly refusal on the phone, Bad Blake heads to
Marfa, Texas, and tracks down his estranged progeny. “It’s a powerful moment, but I didn’t have final cut, and there were folks who said we should cut it -- that all of the information was there in the phone call scene.”
Again with the Marfa, Texas and Heath.
