Superman On Blu-Ray

I picked this up from Costco the other day. The main reason I got it was for the original beginning of Superman Returns. I presume it has him going back to the remains of Krypton. I've seen a shot or two of this from some of the early trailers, but have been waiting to see the entire sequence for years. I read in an interview that Singer chopped 45 minutes out of the entire movie. I'd like to see those 45 minutes replaced, though I suspect much of it was unimportant, or were plot points that didn't make sense after all was said and done.
