While uniting She-Hulk and Daredevil on She-Hulk: Attorney at Law seems fairly logical, it still came as a surprise to the show's writing team when Marvel Studios approved the cameo.

Series creator Jessica Gao told Collider that, when it came to re-introducing Matt Murdock, the vigilante's post-Netflix status initially left her uncertain about a crossover's viability. "I don't think we ever, in a million years, thought that we would be allowed to use them, because we didn't know what the status was of the character," she recalled. "And then, I can't remember how, we got wind that he was coming back and that it was Charlie Cox, and we were like, 'Wait, does that I mean we can use him? Are we allowed? And when they told us yeah, I mean, we couldn't believe it, we thought we were being pranked."

Despite hearing the news of Cox's return -- after officially re-entering the Marvel Cinematic Universe in Spider-Man: No Way Home -- Gao remained skeptical, even while crafting She-Hulk's scripts. "We just kept writing him in, and we kept rolling with the story just thinking like, 'Okay, any moment now they're going to tell us we can't use them. They made a mistake. They actually don't have the rights.' But it just kept [becoming] more and more real. And it was so hard to keep that secret!," she joked.

She-Hulk's newest trailer teased a confrontation between star Tatiana Maslany's Jennifer Walters/She-Hulk and Daredevil in its final moments, despite never revealing Cox's face. In place of his Netflix outfit, the trailer also showed Daredevil wearing a red and yellow outfit similar to his original costume's color palette. Other notable cameos in the trailer included Benedict Wong's Sorceror Supreme Wong and Tim Roth's Emil Blonsky/Abomination, marking his non-transformed live-action return to Marvel since 2008's The Incredible Hulk. The comeback occurs after Roth provided vocals for Abomination in Shang-Chi and the Legend of the Ten Rings, where he and Wong shared a brief cameo as cage fighters in Xialing's Macau-based underground superhuman fight club.

Since his Now Way Home cameo, it has been announced that Cox will voice Daredevil in the animated series Spider-Man: Freshman Year and have a supporting role in Disney+'s Echo spinoff alongside Wilson Fisk actor Vincent D'Onofrio. San Diego Comic-Con's Marvel Studios panel also confirmed that Cox will star in the 18-episode Disney+ reboot series Daredevil: Born Again.

She-Hulk: Attorney at Law follows Maslany's Walters, a lawyer who receives Hulk-like appearance and powers after unwittingly absorbing gamma-radiated blood from her cousin Bruce Banner. In addition to its cameos, the series' trailers have spotlighted She-Hulk's ability to regularly break the fourth wall during her misadventures; a creative testament to the writing team of creator Gao and directors Kay Coiro and Anu Valia.

She-Hulk: Attorney at Law premieres on Disney+ on Aug. 17.
