Fantastic Four: First Steps – Trailer Description:
The trailer is around the 1:43 mark, it opens in a 4:3 aspect ratio but as the scene unfolds, the frame gradually expands to a more modern cinematic look. While the visuals are sleek and contemporary, the production design has a distinct retro-futuristic aesthetic as we saw from the SDCC footage. This is clearly not the MCU but a different universe.
We get a glimpse of the team in action: Sue Storm using her powers and flickers between visible and invisible as she clings to Reed Richards. We see Johnny Storm ignites into his full "Flame On" form. We also see Johnny in human form, drifts in space. Ben Grimm appears both in his human and rock forms.
No Franklin Richards or the Silver Surfer in this trailer but we do get to see Galactus. We get a sense of the story that the Fantastic Four coming together to stop him.
