Sadly, the IMAX projector never recovered. We only got to see just over a third of the Dark Knight in megavision. Regal did reserve a 3:10 showing in a normal theatre for us, which we saw, and gave us two free passes to any Regal anywhere for any show, including IMAX. So, at least they made up for it.
Dark Knight, by the by, was completely awesome. Almost without reproach. Almost.
