Yes, some of the show’s producers are considering a live-action movie, in which their actor of choice to play protagonist Sterling Archer is Jon Hamm.
If Archer goes live-action, I do believe it will be Jon Hamm.
It’s hard to imagine more perfect casting of a cartoon character with a live actor, since Hamm looks much more like Sterling Archer than does the actor who voices him, H. Jon Benjamin.
How serious the producers are about the live action movie, or the Hamm-as-Archer idea, remains unclear.
