First Steps has left Marvel fans giddy, and The Thing — rather than plot conjectures or the exciting action sequences — has taken centre stage.

While the movie looks like a retro-futuristic romp featuring Marvel's First Family, one point in particular has fans debating: the CGI on The Thing. Ebon Moss-Bachrach plays the character, whose real name is Ben Grimm, and we got our first look at him post-transformation in the trailer.

“The Fantastic Four: First Steps” tells the story of Marvel’s first family and stars Pedro Pascal as Reed Richards/Mr. Fantastic; Vanessa Kirby as Sue Storm/Invisible Woman; Ebon Moss-Bachrach as Ben Grimm/The Thing; and Joseph Quinn as Johnny Storm/The Human Torch.
