Only for giving some info about the film,but no footage.

Even a trailer is enough for me. If there is I will go crazy and my Dad will be not as crazy as me but I'll hear him say... " We will see that opening day...no matter what."

Yeah I assumed that's when they'd premiere the trailer, or maybe attached to Harry Potter.
I'm not going this year though, so I kind of hope not, because I'm horrible like that.
