I immediately wanted him to be Ryle.

I just thought that he had what it takes to portray that character.

And the good news is, he’s gonna be Ryle!”

Baldoni teased the film on social media, too.

It’s going to be beautiful.”

These days, Baldoni works primarily as a director.

“It’s a bittersweet goodbye, but a beautiful one,” he said.

In anInstagramvideo in January 2023, Hoover said, “Blake Lively, y’all!

She’s my dream Lily.”

Lively toldColliderthat she’d been cast because fans of the book online voiced their support.

Fans of “It Ends With Us,” on the other hand, aren’t so sure.

Lively is considerably older than Lily is in the book, which Hoover toldTodaywas necessary.

Then came his big break.

“I love the work,” he toldMan About Town.

Shortly thereafter, photos were published byPeopleshowing Minhaj filming alongside director and co-star Justin Baldoni.

Minhaj anchored “Patriot Act” on Netflix, an incisive show that took deep dives into important topics.

His work was so impactful, in fact, that the show won a prestigiousPeabody Award.

Nevertheless, Netflix canceled the show.

He’s released two specials through Netflix, “Homecoming King” and “The King’s Jester.”

If you like something thoughtful with your laughs, then Minhaj is the comedian for you.

Unlike some other roles in the film, fans largely responded positively to Slate’s casting news.

“All of the people there were so kind and wonderful to work with,” she toldSF Gate.

If Slate’s face seems unfamiliar, you still may recognize her voice.

She’s the creator and voice actor behind the viral-hit-turned-acclaimed-film “Marcel the Shell with Shoes On.”

Neustaedter has been working consistently since 2009, so he might seem familiar from a number of projects.

In an interview withAssignment X, he noted that he put on weight for “American Rust.”

“But I liked it.”
