No way this is true
NO actor is getting paid $300 Million Dollars for a film. No matter how popular. NO actor is getting CLOSE to $300 Million for even a franchise deal. Robert Downey didnāt get close to that for the MCU. Will Smith wouldnāt get that for Men In Black. NOBODY.
Even a lucrative backend deal (which many stars negotiate) wouldnāt net any one actor close to 300 Millie.
If Johnny Depp were to come back to the franchise, even if Disney got down on their KNEES and begged; I could see reports of āJohnny Depp signs a two picture deal to return to Pirates Franchise For A Record $75 Millionā plus Backend. But thats the extent.
