10 Upcoming Movie Cameos You Don't Know About

4. Jeremy Renner - Black Widow

Production on Black Widow is set to wrap imminently, and Marvel Studios has typically played their cards close to the chest, all the more so given that it's a prequel movie for a character who, spoilers, recently died.

By far the film's biggest question mark is the presence - or implied lack thereof - of Natasha Romanoff's (Scarlett Johansson) oldest pal, Clint Barton aka Hawkeye (Jeremy Renner), who hasn't yet been officially confirmed to appear. Nevertheless, all the evidence and common sense in the world points to him being in it.

The biggest giveaway above all else is that the production spent time shooting in Budapest, which is of course the epicenter of a mysterious, pivotal event in both Natasha and Clint's pasts, as first referenced in the original Avengers movie.

It'd be absolutely ludicrous not to pay this off in what will presumably be Black Widow's final MCU outing - short of a contrived resurrection, that is. And above all else, how could the Budapest mission possibly be explored without an extended cameo from Hawkeye himself?

Various set spies claim that Renner has filmed a small cameo for the film, which will hopefully reveal the nature of their Budapest sortie in a satisfying manner worthy of its shady rep.
