MyTimeToShineHello, a reliable insider known for Marvel movie leaks, recently posted on Twitter that Robert Downey Jr.'s Iron Man will return in Avengers: Secret Wars.
Another Spanish leaker, Marvel Spoiler, also shared this news, stating that Robert Downey Jr. will not only play the villain Doctor Doom but will also appear as Tony Stark, aka Iron Man.
It's worth noting that earlier reports suggested Robert Downey Jr.'s salary for filming Avengers: Doomsday and Avengers: Secret Wars was $100 million. If he is indeed playing both Doctor Doom and Iron Man, that hefty paycheck might start to make sense.
