Taraji addressed the tik Tok and basically said no beef with big o.
Actor's pay is heavily dependent on if they can get high box office numbers as a lead and at this time Taraji hasn't shown that. She did Proud Mary as a lead and it didn't do well. She said that was the last time she got a pay bump.
She should consider looking at Viola's team who is by far the best in the game. The roles are always a mix of lead and supporting roles that feel like Viola is the lead while adding in serious with a mix of major franchises which opens her up to new audiences. They are on their way to being able to say Viola is critically acclaimed, a box office draw, and has global appeal. Which is all going to push her fee up higher and get it met.
