I just watched the Peter Jackson King Kong the other night (actually 2 nights, as I watched the extended cut which was 3 Hrs 20 Mins) on Blu-Ray.
Good film, good acting, andy serkis as Kong.
Some of the CGI is little dated now, and the extended cut is pretty long, the theatrical is probably the way to go.
Anyways, yeah i would get the steelbook if it had nice art.
