Robert Downey Jr. is returning to the Marvel Cinematic Universe (MCU) as the iconic villain Doctor Doom, rather than reprising his role as Iron Man, with plans for him to appear in 'Avengers: Doomsday' and 'Avengers: Secret Wars'. His return comes with significant financial negotiations, as he is reportedly receiving a hefty raise along with an array of perks. The Russo brothers, directors of Marvel's most successful films, have also been brought back at a cost of $80 million for both films, with performance bonuses tied to box office success. This strategic move aims to rejuvenate the MCU following mixed reviews of recent releases. Additionally, Harrison Ford will make his MCU debut as Thaddeus 'Thunderbolt' Ross in 'Captain America: Brave New World', taking over the role after the passing of William Hurt. Ford shared his experience with the challenges of motion capture technology while expressing excitement about his new role and the film's reception.
