"no comparison," eh? Thank you for undergirding my point. BBC and GBU are two different films. QED.
But the point is that the original is BBC, the rest is derivative and should be evaluated ONLY in comparison with it. (BTW your point about Eastwood's voice is simply ridiculous, as Eastwood, after his first two movies, finally managed to model his voice on Salerno's delivery - that is confirmed also in a Eastwood's bio). You take the dubbing excuse to try to prove that GBU is the real thing. It isn't: verstanden?
