Some additional information on the show has now arrived via That Hashtag Show, including descriptions of the major characters and the actors sought to portray them.
Spike SpiegelAn Asian (or partially Asian) man in his mid 20's to mid 30's and must have athletic ability. Spike is the young and handsome male lead with a body like Bruce Lee. His care free demeanor hides a seriously dangerous individual. Spike is prone to shoot first and improvise, unlike his more serious partner Jet, but he gets the job done. Spike tries to hide his sensitive side but is a sucker for a damsel in distress and is haunted by his past.
Faye ValentineAn Asian (or mixed heritage) woman in her early 20's to mid 30's and must have athletic ability. Faye is the female lead of the show. She is an attractive bounty hunter with a sharp tongue. She's a survivor who will con anyone to get what she wants. Faye has no memory of her early life, including family or friends. So, even though she'll never admit it, she likes working with the other members of the Bebop crew.
Jet BlackAn African American (or partial African American) man in his mid 30's to early 50's. An ex-cop, Jet looks intimidating but is a softy at heart. He became fed up with the corrupt system, but he still catches criminals as a bounty hunter. While Jet believes in the law, he will always back up a friend. Occasionally, he will even relax and have fun.
Radical Ed14-year-old girl, must have athletic ability and short stature. Ed is a 14-year-old computer genius and expert hacker whose talents are indispensable. She is extremely energetic with a child-like wonder and is eccentric, bordering on the bizarre.
Based on these descriptions, it looks like the live-action show will keep close to the personalities and backgrounds of the original characters, although the race or appearance for some may have a new interpretation. In the anime, the skin tone of the core cast was fairly light, although both the art style and the story left room for most of them to be either white or Asian in descent.
Character breakdowns were also provided for Vicious, the primary antagonist of the series, and Julia, a love interest from Spike's past:
ViciousA man in his mid 20's to mid 30's of any ethnicity, with pale skin and white hair. Vicious is the merciless leader of the criminal organization known as the Syndicate. He will kill anyone who gets in the way of his business without a second thought.
JuliaA woman in her mid 20's to mid 30's of any ethnicity. Julia is a sophisticated blonde damsel in distress that has a mysterious connection to Spike. She appears to him in visions and whispers to him about his past. The real Julia is the girlfriend of the merciless Syndicate leader Vicious.
Cowboy Bebop centers around a small team of bounty hunters attempting to find work in a technologically advanced but largely lawless society, which is spread throughout the solar system in a future where Earth is barely inhabitable but space travel has become common.
The original Cowboy Bebop was produced in Japan in 1998 and went on to become a worldwide success and icon of adult-oriented anime, thanks to its drama, humor and sophisticated animation and soundtrack. The show is known for blending its sci-fi setting with Western and noir tropes, as well as various styles of music.
The cast for the adaptation has not yet been selected, but it's now known that Chris Yost will be the writer and that Peter Friedlander and Kris Henigman will be executive producers. Friedlander is known on Netflix as executive producer on Daredevil and Sense8, while Henigman worked as a producer on all of the shows in Netflix's Marvel lineup. Cowboy Bebop is planned to have 10 hour-long episodes and will begin filming in April 2019.
