20th Century Fox used its San Diego Comic-Con 2015 panel to highlight its upcoming Marvel comic book film adaptation slate, which starts with the Fantastic Four movie reboot. A final theatrical trailer for Chronicle director Josh Trank and X-Men: Days of Future Past writer Simon Kinberg’s superhero feature debuted at the event, but has now been made available online for the general masses to watch.

As you can see above, Fantastic Four (2015) take its cues from the Ultimate Fantastic Four comic book continuity (which debuted in 2004), by introducing Reed Richards and Ben Grimm as, respectively, a child prodigy and his loyal friend since they were kids. Cut to years later and the young adult Richards (played by Miles Teller) and Ben (Jamie Bell) are participants in a proper experiment to realize Reed’s dream of traveling to another dimension, with assistance from the seasoned Dr. Franklin Storm (Reg E. Cathey) and his children, Susan (Kate Mara) and Johnny (Michael B. Jordan).

The final Fantastic Four U.S. theatrical trailer has the benefit of footage with completed special effects, meaning that (unlike previous trailers) it properly showcases the eponymous heroes’ newfound powers, gained after their journey to said alternate dimension. The footage also paints a clearer picture of the narrative stakes here, as we see just what massive destruction the transformed Victor Domashev a.k.a. Doom (Toby Kebbell) is capable of causing, with his own new superhuman abilities.

At SDCC 2015, the Fantastic Four cast and crew described the film as being “darker than people are used to” and “more science than science fiction,” when it comes to Marvel comics-based feature films nowadays. There are flashes of humor in the final theatrical trailers (like the movie’s recent TV spots), but at the same time Trank does appear to have crafted a visually and (to a lesser degree) thematically darker superhero movie, compared to your average Marvel Studios production.

However, while a movie such as the upcoming Ant-Man has the brand power of Marvel Studios behind it, and Fox’s developing X-Men films all have ‘event’ status (see: X-Men: Apocalypse), the Fantastic Four reboot has to stand out more as just an extraordinary superhero feature film on its own terms, in order to compete in the current market. ‘Darker and more grounded’ alone isn’t enough to accomplish that, in the modern superhero cinematic landscape.

Trank and Co, despite controversy over their creative choices and what difficulties allegedly went on behind the scenes during production, seem to have put together a perfectly competent addition to the superhero genre (maybe something better than that, even), judging by the latest Fantastic Four trailers. Again, though, the question is: will that be enough to give Fox the critical/commercial success it wants?
