Caught the first showing today of Titanic in IMAX 3D at my local theater. I thought it was a spectacular presentation. The 3D conversion was excellent. No cheapo post conversion here. The depth present in some of the shots was very impressive. I kept looking for flaws and couldn't find any. The soundtrack seems to have been remastered as it was crisper and cleaner (and louder) than I have ever heard before in the many times I saw it theatrically in 1997 and 1998. For instance, during the post sinking scene with all the passengers in the water, cries for help were heard from all directions and you could clearly hear what they were crying. The film itself holds up extremely well. I thought perhaps it would feel somewhat dated in the 15 years since it's release, but was I pleasantly surprised at how briskly the time flew by. A note on the IMAX AR. I was expecting a 2.35:1 ratio on the IMAX 1.44:1 but was surprised to see it projected at approx 1.33:1 almost completely filling up the IMAX screen. I believe the film was shot in Super 35 so Mr. Cameron apparently opened up the frame for IMAX. I didn't notice any picture loss and I know the film pretty well but I'm not sure. Nevertheless it worked and looked great. Definitely worth seeing if you're a fan, or have never seen it theatrically.
