For yourself hb, and anyone else who knows, what are Docs supporting characters like and what actors would you like to see cast?
Doc has five sidekicks, often collectively known (albeit not in the novels themselves) as the Fabulous Five. (It has been speculated that the Fantastic Four may have been partially inspired by the Fabulous Five).
Andrew Blodgett "Monk" Mayfair. A short, apelike chemist. He's very muscular, a bit rude and grumpy, and has a sarcastic sense of humor. Think of a human version of the Thing from the Fastastic Four. As for who to cast as him, I don't know of anyone that quite matches his physical characteristics. Maybe Andy Serkis or Michael Chiklis under a ton of prosthetics?
Theodore Marley "Ham" Brooks. A sophisticated lawyer with an impeccable sense of style and a hint of arrogance. He and Monk bicker nearly nonstop (the two have a feud that goes back to WWI, when Monk allegedly framed him for stealing a ham). Maybe Jude Law or Tom Hiddleston.
John "Renny" Renwick. A gigantic engineer with a glum, puritanical face. He towers over even Doc himself, and has extraordinarily gigantic and powerful fists. The happier he gets, the more sour-faced he looks. Michael Shannon certainly has the glum part down pat, although he's a bit smaller than ideal.
William Harper "Johnny" Littlejohn. A tall, thin geologist with black hair. He started out with a monocle (having been blinded in one eye in WWI), but later got glasses when Doc fixed his blind eye with surgery. He's fond of using big words and using such exclamations as "I'll be superamalgamated!" I'm not sure who could play him.
Thomas J. "Long Tom" Roberts. A pale, sickly-looking electrical engineer. He's stronger and healthier than he looks. I'm not sure who could play him either.
Also, Doc's cousin Patricia "Pat" Savage made occasional appearances. She had bronze skin and hair like Doc (although the bronze color of her skin was milder than that of Doc's). She was feisty and strong-willed, and would sometimes tag along on adventures even if Doc didn't want her to. I could see Elena Satine or Katheryn Winnick in the role.
