Fox has released a new trailer that gives a feel for the characters and storyline, plus a glimpse of Doctor Doom.  A new poster was also released.

The last (Japanese) trailer was more focused on the superpowers (see "Japanese 'Fantastic Four' Trailer Teases Superpowers"), and this new expands on that as well.

The movie will be released on August 7, 2015 (see "Best in Shows--Q3 2015").
