Rae was salty that RZA turned down the Leonardo Dicaprio deal. Leo was probably gonna be in the movie and Rae saw dollar signs. RZA told him if he could find a deal that he would listen but Rae believes RZA didn't think Rae would actually find anything legit. So, when he showed up with Leo and RZA dismissed it, Rae was hurt pretty badly by that. He says they were gonna make the show without his character in the show, and he says there was a teaser of the making of Cream without Rae there. That's when Rae said he told them he was gonna sue them. RZA worked out the money and then Rae met with Shameik. Rae is mad the other Wu members aren't listed as producers, and made it sound like him and them have no input in the show.
That's fabricated for the book as well. I posted the BC interview when he said what happened. First off, Rae thought the movie could be made with 10M. Rae just wanted a movie. RZA did tell him to see what he could do, and RZA ended up having several meetings with Leo's team trying to work out the logistics after Rae brought them in. In the end, he had to sign off on the show before they could work out the kinks for a movie. Rae was just salty cause he wanted a movie, and wanted that producer payment. Looking back he may have felt that RZA wasn't gonna do the movie, but you can't say it wasn't given serious thought.
Another instance is RZA was right. No way could you include 10 rappers, Math, Divine & Power all in a 2.5 hr movie. I want to see this teaser. There's no reference to CREAM in season 1, so if anything, it was probably a pitch to gauge the tone of the show. There's probably no Clan members in it
And I doubt Rae knows or cares about other's involvement. According to RZA the writer's room is open to them...Meth been on set and Ghost said he's spoken to the writers a few times, Divine has hella input...and other members said they've been in contact with their actors and storylines.
