10 Movie Moments Everyone Was Waiting For (That Never Happened)

10. Tom Cruise's Iron Man Joins The Illuminati - Doctor Strange In The Multiverse Of Madness

While he would more than make his presence felt in the heat of this summer's blockbuster box office battle with his $1 billion mega-hit return to all things Maverick, a great many fans were actually expecting to witness Tom Cruise shake-up the cinematic system a few weeks earlier during a certain MCU offering.

On the back of Patrick Stewart's Professor Xavier making a jaw-dropping appearance as the assumed leader of The Illuminati in trailers for Doctor Strange in the Multiverse of Madness, rumours of Tom Cruise rocking up as a Tony Stark/Iron Man variant - acting as a knowing nod to his almost-casting as the hero years earlier - began to understandably intensify.

The reveal of John Krasinski as an alternate universe Mr. Fantastic during the flick, another MCU fan-casting come to life, only seemed to add more fuel to this fantasy, too.

But despite the film's screenwriter Michael Waldron actually running this much-wanted development by Kevin Feige, he'd later inform Rolling Stone that Cruise was likely never a possibility due to his shooting of the next few Mission: Impossible flicks at the time.

Sadly, this mission was simply impossible for Waldron and the rest of the Marvel team to pull off.
