As far as 'holes' in the numbers, I would say with VHS/DVD/Blu-Ray sales this would be another analysis point that captures post-cinema revenue results. But the details are not always clear, depending on how much per-title tracking was in place at a given point in time. So my current analysis focused on what could be a common comparison - cinema results.
With taking the approach of subtracting special profit-sharing arrangements, it would be interesting but also tricky. We would have to know all arrangements that involved DC and Marvel movies to make it fair.
And what about advertising revenue like 'Man of Steel' and its $170 MM success? Again, it would be interesting. But not all movies reveal this information clearly. But it must have had an impact, as now 'X-Men: Days of Future Past' is going like gangbusters with its Carl's Jr/Hardees TV and print ads.
