So, they can't run an
advertisement for a movie (i.e. Avengers or Iron Man monorail) in a theme park due to the Uni contract but they can show actual
screening of a movie? I'm sorry, but I call shenanigans. Jim Hill might have said that but it doesn't pass the sniff test. If GotG were limited the way Iron Man, Hulk and the rest of the Avengers were, we would not have seen them in the parks in any capacity. If a simple movie billboard on monorail is not allowed in a park for a property, then nothing is.
Besides which, insiders on these pages have already indicated that Disney lawyers
determined that GotG could be used in WDW.
