It's not hard, folks. Compare these poster for Pirates of the Caribbean: Dead Man's Chest and Pirates of the Caribbean: At World's End, Pirates of the Caribbean: On Stranger Tides. Dead Man's Chest scores an impressive 3 for 3 accuracy rate while At World's End goes a shameful 1 for 5. This is floating head art. How hard is it to merely choose accuracy over the branching-out system? You want to keep Johnny Depp at the forefront? Fine, but what mess up the accuracy of everyone else, resulting in poor Keira Knightly being mistaken for Orlando Bloom!
New Line Cinema has been a longtime proponent of accuracy in poster labeling. Even with the Rush Hour sequels, which had two posters where each respective star got top billing, each poster made sure that Jackie Chan and Chris Tucker was placed at the proper labeling slot. So too did the one sheet for Se7en, which correctly put Brad Pitt on the left and Morgan Freeman on the right to account for their billing order.
I'll leave you with one more, which went 1 for 5 in terms of correctly positioning the actor in the vicinity of their respective billing. This isn't a case with actors being off on their own agenda on the photo-shopped poster art, or even a case where the cast billing goes elsewhere on the art. This is poster art of the floating head or full-body cast list that still manages to royally screw up synchronization. Write your congressman. Take action now to end this terrible epidemic of poster positioning screw ups! It's up to you!
