Justin Baldoni urges Disney to keep records that can substantiate his accusations of being targeted by Ryan Reynolds through Nicepool.

Justin Baldoni is seeking to gain communications made about Ryan Reynolds‘ Nicepool character in an attempt to show it was used to “bully” him.

As the It Ends With Us director-actor’s legal battle responding to costar Blake Lively‘s sexual harassment and retaliation claims advances, Baldoni’s lawyers sent a litigation hold letter on Jan. 7 to Marvel Studios president Kevin Feige and Disney CEO Bob Iger, demanding they hold onto documents that mention Baldoni for potential use in court.

According to the letter, viewed by PEOPLE, they want “any and all documents relating to the development of the Nicepool character” and “communications relating to the development, writing and filming of storylines and scenes featuring Nicepool.”

To support his claim, Baldoni’s legal team is looking for documents “relating to or reflecting a deliberate attempt to mock, harass, ridicule, intimidate or bully Baldoni through the character of Nicepool,” among other subjects.

A rep for Reynolds and Lively could not be reached by PEOPLE for comment. A spokesperson for Disney did not respond to a request for comment.

Nicepool is a minor character that Lively’s husband Reynolds plays in Deadpool & Wolverine, the blockbuster 2024 film that Reynolds also co-wrote. The character, complete with a man bun, describes himself as a “feminist” in the film and calls the character Ladypool, played by Lively, “gorgeous” and says, “She just had a baby too and you can’t even tell.”

Lively, 37, has sued Baldoni, 40, accusing him of sexual harassment and plotting a smear campaign in retaliation to coming forward about misconduct. Among other claims, Lively alleges in her complaint that Baldoni found “back-channel ways of criticizing her body and weight” after she’d recently given birth to her fourth child.

Additionally, a purported deleted scenes making the rounds on social media shows the Nicepool character saying that his “calling is to one day start a podcast that monetizes the women’s movement.” Baldoni hosted a podcast called Man Enough since 2021 that discussed “modern masculinity.” His co-host Liz Plank left the podcast after Lively’s complaint came to light.

Baldoni’s lawyer Bryan Freedman spoke to Megyn Kelly, one of his former clients, on her web show earlier in January and claimed “there’s no question” Nicepool “relates to Justin.”

Baldoni has denied Lively’s claims. Freedman has said Baldoni plans to sue Lively and others soon, and he already filed a $250 million lawsuit against The New York Times over its coverage of Lively’s complaint in December.

In a statement, Freedman claimed the outlet “cowered to the wants and whims of two powerful ‘untouchable’ Hollywood elites,” meaning Lively and Reynolds, who wed in 2012 after meeting on the set of Green Lantern. (The Times stands by its reporting and says it’ll “vigorously” defend against the lawsuit.)
