Watching the Gollum DVD in the TTT box set, you get to see PJ's motley collection of LOTR statues. Ok his other statues/kits would make any toy shop owner think they were back at work... but..
Lee apparently says that he likes the depiction of himself as Saruman, and congratulates the SSW team on getting his best likeness. SSW make the bronze version for him specifically, because he likes the poly version so much.
If McKellan had the bronze Gandalf, would he be a snob? (ok so it doesn't look like PJ's Gandalf, but u get the gist)
Actually, considering that the cast could probably get the statues at a great discount anyway, I was surprised how few some of them had.
Unless of course the statues mostly weren't 'theirs' just product placements for the DVD to lure newbies into their web...
