Jon Hamm Reveals Why He Missed Out On SUPERMAN RETURNS And Playing THE NEW MUTANTS' Mister Sinister

Onward star Jon Hamm has opened up on nearly being cast as the Man of Steel in Superman Returns and his brief flirtation with the role of Mister Sinister in The New Mutants.

Jon Hamm's name is often linked to comic book adaptations, but how close he's actually come to any of those projects is hard to say. We know that the Mad Men star was eyed to play Superman once upon a time, while 20th Century Fox also wanted him to tackle Mister Sinister.

In the case of the latter, the plan was for Sinister to debut in The New Mutants, likely becoming the franchise's new big bad once the main X-Men movies finally caught up to the present day in the wake of Dark Phoenix.

The Disney/Fox merger brought a swift end to those plans, of course, and Hamm briefly commented on what might have been while speaking with Josh Horowitz. "That was supposed to happen and didn't," he confirmed. "I think there was some corporate craziness that went on, and they sold the studio, and Disney bought the studio."

The extent of Fox's plans for Hamm as Mister Sinister will likely remain a mystery, as the studio never really planned ahead while mapping out its Marvel movies. When the X-Men franchise is rebooted for the MCU, Sinister is expected to be put front and centre.

As for his near-miss with Superman, Hamm confirmed that he was in the running to play the Man of Steel in 2006's Superman Returns. The lead role in that ultimately went to Brandon Routh. 

"My pitch for the Superman thing was like, 'What if Superman was funny like he used to be with Christopher Reeve?' And they were like, 'Great idea. We're going to do that two more Superman's later,'" Hamm joked, referencing James Gunn's 2025 reboot.

When we spoke to Hamm in 2022, we asked about Mister Sinister and his interest in comic book movies. "Yeah, I don't know. Sometimes I find out more about my career from the internet than I actually find out from my agents," he shared. "So, I didn't really know that was in the works until somebody told me that I didn't get it or it didn't happen."

"I really don't know. Like anybody else, I would be thrilled to be part of that storytelling having been a big comic book fan throughout my early teens and early twenties," Hamm said of Mister Sinister potentially crossing his radar again. "So, we'll see. I don't know. It would be a fun person to play, that's for sure. I look good in purple, I'll put it that way."

Who would you like to see Hamm play in the MCU or DCU? Let us know your thoughts in the comments section.

2013 to 2020 Jon Hamm would have been excellent as Kingdom Come Superman. Now we're taking the long way around. Oh well...

@UltimaRex - Yes, I always thought he was a shoe in for an Alex Ross iteration.

He could definetly still pulloff an aged, weathered Supes. Or Bats.
He has the hairline and the jawline

Sometimes i imagine what Superman returns could of been if he was a new Superman altogether.

I thought it might be related to him torturing that guy in university. The guy is a monster.

Oh , some people on here won’t like his “what if Superman was funny” comment and to that I say…

Anyway , he could have made a good Superman but is just too old now imo unless they make an Elseworlds Kingdom Come adaptation which i don’t see happening.

Also in regards to Mister Sinister , I still think he could pull it off so hopefully Marvel doubles back to him for the role when X-Men casting really heats up if the character is in the film that is!!.

@TheVisionary25 -

My pick for Sinister remains Tom Ellis, or more recently Theo James.
TheVisionary25
TheVisionary25 - 4/7/2026, 8:29 AM
@TemporarilyHere - two good choices.

Ellis remains my preferred but while Hamm wouldn’t be my ideal pick , I could see him pull off the character.

My DC fancast choice for him now:

Christopher Chance/The Human Target.

Going through my first watch through of Mad Men, and Hamm’s an absolute beast. Incredible performance. Loved him in Top Gun & Baby Driver too.

@tmp3 - "Loved him in Top Gun & Baby Driver too." He was Excellent in both and Really excelled in Baby Driver. I also found him to be great in Keeping up with the Joneses

@MotherGooseUPus - You should check out Mad Men too if you haven’t. Incredible TV, and Hamm gives an all time great performance

Mad Men is one of those shows that, while undeniably great, unfortunately left a negative cultural impact on their greater audience, a'la Rick Sanchez or Walter White, or more recently Thomas Shelby.

But yeah, Hamm's phenomenal.

He's so [frick]ing good in Mad Men, dude. We finished it about a month ago and I'm still trying to fill the void. He's entered the pantheon of actors who was just so perfectly cast they've reached their APEX - he's so good in TG2 but Don Draper was such a perfect role for him. Him, Cranston, Gandolfini are all in that tv anti-hero HOF for me.

How far into Mad Men are you?

@tmp3 - his intoxicating charm is once again on display for Your Friends and Neighbors on Apple TV and it's pretty entertaining. Obviously it's not as good as Mad Men but it scratches that itch

@TemporarilyHere - I think Don Draper really is a sad, insecure boy playing dress-up in a way that Heisenberg, Patrick Bateman, Shelby and Tony Soprano never were - so I don’t think he gets the same level of idolization as those guys seemingly do

@regmovieguy - Finished season 3 but got also my girlfriend hooked on it, so I’ve been holding off until she’s caught up so we can see it together. She’s on s3 ep7 so i should be able to start s4 p soon. Incredible performances all around; can’t forget Slattery, Hendricks and the dude playing Campbell (“It’s called a chip & dip” plays rent-free in my head)

@bobevanz - Might just have to see it now for Hamm. Heard Marsden joined season 2, sounds like a fun cast

@tmp3 -

Respectfully disagree, especially in regards to dress-up.

Walter's fedora and the Shelbys' caps especially are pieces of attire that even in their respective shows are given symbolism, which gullible audiences sadly seemed to have drawn all the wrong conclusions from.

Can't speak about Sopranos since I haven't watched it.

They're all perfectly cast, haha. Campbell started out as such a little shit, too, he turned into one of my favorites.

@tmp3 - it's been on my must watch tv list for a very long time and i haven't gotten around to it. I've heard he is Phenomenal in the show; and the show is excellent as well.

Having had no complaints from Pascal, Hamm would have been excellent. He's got mad range as an actor, and surprisingly gret comedic timing to play off of Ben.

He would have been great as Sinister, to be honest.

I always felt he was better suited for Bruce and Batman, to me he looks like a Bruce. But I wouldn't have minded him as Clark.
