Terrence Howard & Robert Downey Jr.
You might know this duo from the Marvel film Iron Man, where Robert Downey Jr. played the titular character. Tony Stark and Terrence Howard portrayed the superhero’s loyal aide, James Rhodes. Unfortunately, the latter, who announced a new project in 2020, was replaced by Don Cheadle.
Known for being ill-tempered, Howard was let go by Marvel and had given him a measly salary, all of which he blamed on Downey. The rapper claimed he helped his previously troubled pal land the Iron Man role, but he wasn’t there to support him. In 2017, Howard hinted that the feud was over through an Instagram post.
