On the one hand, it's surprising that none of the people involved in creating, publishing, and marketing this trailer raised an eyebrow. I don't know much about film history but I raised an eyebrow. And presumably, it took MANY people to make this trailer happen, and a good chunk went to film school or otherwise know enough to know that this was fishy.
On the other hand, things like this likely get caught during production all the time and we just never hear about them.
