After over a decade in the MCU, Robert Downey Jr. knows secrecy is key, meaning he won't confirm or deny an appearance in the long-awaited Downey Jr.'s unofficial retirement from the MCU, it's unknown if he'll appear in future Marvel films.

Confusing matters even more, Avengers: Infinity War. Plus, like Iron Man, Black Widow sacrificed herself in Avengers: Endgame, meaning Black Widow is already allowing one character to return from the dead.

Downey Jr. is currently promoting his new film Dolittle, and, unsurprisingly, there have already been questions about his future in the MCU. Per Entertainment Tonight (via CBR), when asked specifically about an appearance in Black Widow, Downey Jr. replied, "It'd be nice if they'd notified me... they can do anything now. This could be a deepfake interview for all we know!" Instead of responding one way or another, Downey Jr. didn't actually answer the question, meaning an appearance in Black Widow could still be on the table.

Whether Iron Man returns in Black Widow or not, excitement for the film, which comes out this spring, is at an all-time high. Fans have been clamoring for a solo film starring Scarlett Johansson's Stranger Things).

Though Downey Jr.'s comments ultimately don't prove or disprove a possible return in Black Widow, they do indicate it's still a possibility. Playing coy about cameos has long been an important aspect of the MCU machine. Since the source material for the films is obviously readily available via the comics, Marvel creatives and stars have to do what they can to keep things a surprise for fans. Black Widow already looks to be an exciting entry in the MCU, but a cameo from Iron Man himself could be the cherry on top.
