8 Actors Whose Careers Flopped After Leaving The MCU

5. Shaun Toub

Iron Man Yinsen Death
Marvel Studios

As Yinsen in the original Iron Man, Shaun Toub gave one of the most overlooked, understated performances in the entire MCU.

Without his aid, Tony Stark wouldn't be the man he is today, and by extension, the MCU wouldn't be the same. By reminding Tony that he didn't have anyone who he truly cared for, Yinsen gave the billionaire a fresh perspective on his life, leading him to care about people, and not money, booze and partying.

Yinsen later appeared in Iron Man 3 for a handful of seconds (a callback to a scene in Iron Man, where he explains that he'd met Tony before), but this aside, Toub's career very much peaked with his role in the MCU's first ever movie.

Immediately after Iron Man, things did look promising. Toub was set to appear in M. Night Shyamalan's The Last Airbender, a blockbuster adaptation of the popular animated series. But we all know how that turned out: the movie was a complete failure in every conceivable way, and since then, the actor has been relegated to bit-parts in small movies, and some TV work.

Danny has been with WhatCulture for over ten years, and is currently Doctor Who Editor and WhoCulture Channel Manager, overseeing all of WhatCulture's Whoniverse coverage. In 2022, he took charge of WhoCulture and has grown it into the biggest Doctor Who channel on YouTube, and one of the biggest Doctor Who communities on the web full-stop. He has been writing and video editing since his early teens, and first got a taste for content creation after making his own Doctor Who trailers, off the back of a burning obsession with the Matt Smith era of the show. Like many his age, he first got into Doctor Who with the 2005 revival, but has since gone back and fallen in love with the classic years too. If you need someone to recite every Doctor Who episode in order, or to give you a random factoid about the making of Gridlock, Danny is the person to ask!
