Marvel Studios released the first full look at Tatiana Maslany and Mark Ruffalo in the official trailer for She-Hulk almost three months ahead of its Disney+ debut. She-Hulk marks a key turning point for the MCU as a brand-new heroine takes her position in Phase 4 as the first Hulk-centric project in the MCU in over 14 years.

It’s the first project, streaming or theatrical, to showcase a starring character brought to life with as much CGI as Jennifer Walters, who is part of what makes this series such a game-changer for the MCU. Even with the amount of CGI work Marvel Studios does on most of its films, which has increased in Phase 4, another gigantic green monster of a heroine is a major undertaking for the MCU. Sean Ruecroft, VFX artist for the She-Hulk: Attorney at Law Disney+ series, took to Twitter to explain some of the developments behind She-on-screen Hulk’s design.

Ruecroft responded to a Tweet by saying that the 6-foot-7-inch-tall heroine had a more muscular build earlier in the process, until the Marvel Studios creative staff repeatedly told the visual effects team to “make her smaller”:

“I worked for a VFX business at the time. She was apparently bigger at first, but the notes kept telling her to’make her smaller.’ We constantly roll our eyes (as we did with Sonic), but artists must follow commands at the end of the day.”

It’s never easy to get the sizing right on characters that are entirely created with CGI, especially the bigger ones like Vin Diesel’s Groot or Mark Ruffalo’s Hulk. Even with a reference point for She-Hulk in a comparable character to the Hulk, the VFX department’s heavy-handedness presented a fresh set of problems for the show’s crew to deal with.

In his initial description from Disney+ Day 2020, Kevin Feige defined the figure as “far over 6’7,” when the Hulk typically stands between seven and eight feet tall. When Bruce Banner figured out his Smark Hulk persona, Marvel Studios used that as a baseline for where to put She-Hulk, and it altered and eventually settled into something constant.

At this time, it’s unclear why the studio and the VFX department had some concerns with the character’s scale, though fans may never know the true causes for those issues. The only hope is that her height doesn’t detract from the show’s overall suspension of disbelief, especially since the CGI will continue to improve until the series is completed.

On August 17, She-Hulk: Attorney at Law will premiere on Disney+.
