Makes you wonder what Hollywood will do with the Dambusters remake. Could a B-17 have lifted Upkeep? Brad Pitt for Gibson maybe?

That's not Hollywood though, and is being made by someone with an historic appreciation.

Apparently Mel Gibson originally acquired the rights with the idea of directing it so a Hollywood version was not so far-fetched. People tend to forget that there were a lot of Commonwealth aircrew in RAF Bomber Command & 617 Squadron had its fair share of Australians, Canadians & New Zealanders. Apologies to any that I've left out.
Is there any news on progress? The last I heard was back in 2006. Peter Jackson will be the producer with his protege Christian Rivers directing. Sir David Frost was involved as executive producer & Stephen Fry writing the script.
It will be interesting to see how it turns out. Very difficult to improve on a classic even if the original was in black & white. That adds to the authenticity for me. I read somewhere that they had already started work on full-sized Lancaster replicas. The main difference will be that they had real Lancasters available for the original film. CGI is very clever now but it cannot take the place of the real thing.
Unfortunately I suspect the whole project will be overshadowed by controversy over the name of W/Cdr Guy Gibson's dog. Whatever they decide to do it's a no-win situation.
