Robert Downey Jr. first played Iron Man in the titular 2008 film and went on to reprise the role in two sequels and multiple ensemble Avengers films including Age of Ultron and Infinity War.

In a five-star review of Avengers: Endgame, NME wrote: “There really is very little that could be improved about Endgame. There’s certainly no more that could be thrown at it.

“Whether your heart belongs to the original team or one of the newbies, you’ll see them get their time to shine. You will almost certainly cry. Probably more than once.”

The review continued: “Is it the best comic-book movie ever? The Dark Knight could give it a very good fight, but Endgame has more fighters on its team. It might just win.”

In other Marvel news, WandaVision star Elizabeth Olsen recently said that her co-star Kathryn Hahn gave her a box of magic witch stones after the Disney+ series finished shooting.
