OK, the shooting had a huge effect.Many may argue that it had little effect and TDKR having no Joker or Heath Ledger's death is the main cause. However, TDKR is the sequel to TDK, which should make up for that. Plus, TDKR is showing in more IMAX screens, which should have given it a 10M lead over TDK during OW.I have been tracking the tracking of TDKR for a few months. At boxofficebuzz.tumblr.com it was in the mid to high 180s for few months, and went up to 195M just before release, indicating a OW of over 190M with 200M very possible. MTC and RS were showing 185M or so. If it opens to "only" 163M or so, the shooting had at least an effect of 20M, possibly as high as 40M.
