Honestly, I've read all the arguments and sides, on RPF and the den, and I'm convinced there are 2 moulds of varying accuracy. The US mould and the UK mould. Masks coming from the UK mould seem to have a dimensional c-scar. Those from the US mold (Rick Baker mould, EFX) seem to have had that filled in on the original mask prior to the mould being made back in the 70's.
That is absolutely not true.
The baker mold was taken right at the end of filming and the UK mold was taken at the beginning of the ESB production.
Neither of them have a dimensional scar because it was a painted artifact on the original helmet.
The cheek was drybrushed in gunmetal to give a weathered appearance. It is not physical damage that you are seeing.
What does it really mean? EFX was fortunate to get access to an original mould, period. Is it the most accurate? Certainly not, and even if it were this will still be a mass produced piece that was to some degree cleaned up by the necessity of making these creatable in a factory.
I would say yes, the original mold that eFX used (the baker mold taken directly off the original ANH) absolutely without a doubt IS the most accurate. There is nothing else out there that would have been a better base for eFX to use. No question.
I also want to take a moment to apologize for all the bickering that some have witnessed on the RPF.
The short version is simple.
There are a couple small groups of people (maybe 8-10 very vocal people) out there who have helmet castings that they considered to be the best available.
The eFX now comes along and is superior to their castings, and is also available to the masses making them feel less special. So basically they went on a crusade to rubbish the eFX casting and somehow try to skew facts that would make their castings appear to still be superior when in reality they are not.
Also, these two small groups have a long long negative history with me and are not at all happy that I'm working in an official capacity for eFX. It is jealously at it's worst.
Jealous that I'm the one who worked on the project and not them, and jealous that a helmet of this level will be available to the masses which is superior to their own.
