The /J?

ITC Blair?

I thought so but there quite some differences like the G for example.

There is no G in your sample -- and no J, for that matter.

Suggestion: take an additional screenshot and post it here if you want people to I.D. it.

Even helpful people won't neccessarily have the patience to watch an entire trailer to help I.D. a font.

Please take some specific screenshots of the trailer and attach them here, to be sure what you are looking for.
