Actually, when I read IF I DIE BEFORE A WAKE, I was struck by how much it was like Welles movie. Of course, there are quite a few changes as well, but nothing like reading Welles comments would indicate. I'll let you borrow the book if you'd like to read it. And incidentally, Arthur Bannister's crutches seem to have been borrowed by Ian McKellen for his role in THE DA VINCI CODE... and like Everett Sloane McKellen gives a great performance with them!
And on another note, this new Aussie western THE PROPOSITION was really quite wonderful... Danny Huston plays the bad guy, who like Harry Lime doesn't make his appearance until the 2nd half of the movie, and when he does appear he becomes a sort of a Kurtz in the 1880's Outback...
It's also beautifully shot, acted and directed.
