Dream Casting is an imaginative look at the casting process of potential Hollywood projects based on comics and other media. This isn't just about what is being made; this is about what should be made, and who we think should be the stars.
There hasn't been a solo Hulk movie in 10 years, even though everybody loves the version of the character who appears in the Avengers movies and Thor: Ragnarok. I think after the follow-up to Infinity War, it will finally be time to make that happen.
As for the source material, you can't do much better than The Immortal Hulk, the current Hulk comic by Al Ewing and Joe Bennett, with covers by Alex Ross. It's a darker take on the character, in which the Hulk takes violent revenge on anyone who hurts other people. As the title implies, it's also premised on the idea that the Hulk doesn't stay dead if he gets killed, which means you could still make this movie even if he dies battling Thanos.
Mark Ruffalo as the Hulk
Honestly, Mark Ruffalo is so good that I can't even imagine a different live-action Bruce Banner. His take on the character is the number one reason they really should make a Hulk film of some kind happen.
Amanda Warren as Jackie McGee
Amanda Warren just made a strong impression on USA's The Purge series, and she'll be very believable as a relentless investigative reporter.
Peter Sarsgaard as Walter Langkowski
Peter Sarsgaard (The Looming Tower) is a great actor who can pull off the unique mix of intelligence, smarm, and ultimately desperation that defines the hero known as Sasquatch in this story.
Peter Krause as Doctor Frye
Peter Krause (911) does a lot of TV drama, but I think he'd be an interesting presence in a superhero film. Also as Frye he'd spend a lot of time as a glowing deadly skeleton, which would be an interesting new kind of role for him.
Cody Christian as Hotshot
Cody Christian (Assassination Nation) has the generically handsome, youthful looks of this ill-fated gamma-powered young man, and if they find a way to play with how different witnesses see him differently, he can probably handle that too.
Willem Dafoe as Brian Banner
Bruce Banner's father is a creep, but here he's not really the same sort of haggard creep we saw Nick Nolte play in Ang Lee's Hulk. Willem Dafoe (Spider-Man, Murder on the Orient Express) is great at playing grinning madmen, so he can definitely handle this.
Elisabeth Moss as Jennifer Walters
Bruce Banner's cousin Jen is a Hulk in her own right, but in human form she's quite petite. Elisabeth Moss (The Handmaid's Tale) fits that mold, and she's also a really great actor. Seeing her mocap performance of Jen's big green form would be incredibly interesting.
Michael Kenneth Williams as General Fortean
Michael Kenneth Williams (The Wire, Hap and Leonard) is a formidable presence with an air of weariness, just right for the leader of the government's anti-Hulk task force.
Todd Grinnell as Doctor Clive
On Netflix's One Day at a Time, Todd Grinnell has proven how good he is at being annoying, and as Doctor Clive he'll be that much more annoying, and also evil.
Sunita Mani as Doctor McGowan
Clive's assistant is considerably more likable, but that will be even more true with the effortlessly charismatic Sunita Mani (GLOW) in the role.
