Hey peeps. The domes are absolutely the same length. When I have more time I'll post film facts etc etc...
As far as the statement from the sideshow rep is concerned, I'm sure he's (or she) is reiterating the justification of the sculpt... But that doesn't mean it's correct. I won't sit here and name all the inaccuracies Sideshow has done in the past, but if the Big Chap is not 18" long... Then the size is inaccurate.
And just food for thought for those that doubt my "opinion" on the matter. Both Sideshow Lifesize busts of the big chap and warrior were done to correct length of 36" EACH (a fact that impressed me when they were manufactured). That, they got correct.
Not starting a war here peeps, just an obsessed fan trying to shed light on something. Sideshow is NOT always correct.
