At a Syfy holiday party in New York, the casts of Childhood's End and The Expanse gathered with executives and select press to celebrate as those debuts are both less than one week out. Julian McMahon plays Rupert Boyce in the former, based on the Arthur C. Clarke novel, marking a return to science fiction for the actor.

Of course, he played Doctor Doom in the pair of original 20th Century Fox Fantastic Four films, in 2005 and 2007. Many of his castmates have gone on to play other comic book characters since then, with Jessica Alba in Sin City, Michael Chiklis on Gotham, and of course, Chris Evans has found incredible success as Captain America in the Marvel Cinematic Universe.

But when I asked McMahon if there was another comic book character he'd like a crack at, his answer was the same as it's always been: Doctor Doom.

"It's interesting, I was thinking the other day, and I looked online and looked at the new Fantastic Four movie, and I saw it, saw the trailer and I just thought, okay, that's interesting," McMahon said during an interview with ComicBook.com. "But I never got to express Doctor Doom the way that I saw Doctor Doom."

After we talked about the canceled sequel to the reboot (what a weird thing to imagine) and even the possibility of Doctor Doom and the Fantastic Four returning to Marvel Studios, his eyes lit up.

"If Marvel Studios got Doctor Doom back, and I could play him the way I always wanted to, as a sniveling, conniving, freaky guy, I would do that for sure. The character I most want to play is the character I've already played!" he said with a laugh. "There's so much there!"

Stay tuned for more with McMahon about his return to science fiction, his love of comics, and what to expect from Childhood's End.
