Robert Downey J has one of the most amazing comeback stories in Hollywood. Just when everybody thought Downey Jr was history after a series of drug, alcohol and legal issues, he had a massive turnaround thanks to his performance as Tony Stark or Iron Man in MCU.

By the time he retired from the role after Avengers: Endgame, he had become one of the best-known faces in the world — this time for good reason.

But now fans have expressed concern after watching a video he shared on Instagram. In the video, he is wearing a T-shirt from his own venture called FootPrint Coalition and flexes his biceps before laughing and letting go.

In the video, Downey Jr, 57, is clean-shaven, looks noticeably thinner than usual and his hair, visible only slightly from a baseball cap, is greyish.

In comments, a fan expressed dismay, writing, “Its sad to see him getting old.” Another wrote, “THATS RDJ???,” they commented. Another fan wrote, “He’s getting old” and added crying face emojis.
