 In July 2009 , Penn talked about the crossover process , stating , " My job is to kind of shuttle between the different movies and make sure that finally we 're mimicking that comic book structure where all of these movies are connected . . . There 's just a board that tracks ' Here 's where everything that happens in this movie overlaps with that movie ' . . . I 'm pushing them to do as many animatics as possible to animate the movie , to draw boards so that we 're all working off the same visual ideas . But the exigencies of production take first priority " .
