Showtime's TV adaptation of longrunning video game franchise Halo has added six castmembers, according to The Hollywood Reporter.
The six actors - Natascha McElhone, Bokeem Woodbine, Shabana Azmi, Bentley Kalu, Natasha Culzac and Kate Kennedy - have singed on in named roles to join the previously cast Pablo Schreiber (Master Chief) and Yerin Ha (Quan Ah).
McElhone plays both Dr. Catherine Halsey and Cortana, the game's ubiquitous AI guide who, in the show, "may be the key to the survival of the human race."
Woodbine, Herman Schultz in Spider-Man: Homecoming, will play Soren-066, a "morally complex privateer at the fringes of civilization" with ties to Master Chief.
Meanwhile, Indian actor Shabana Azmi will play Admiral Margaret Parangosky, "the head of the Office of Naval Intelligence."
Kalu will play a totally new character, Spartan Vannak-134, described as a "cybernetically enhanced soldier and de factor deputy to Master Chief."
Culzac will also play a newly-introduced character, Spartan Riz-028, whom the Hollywood trade calls a" focused, professional and cybernetically augmented killing machine."
Rounding out that trio, Kennedy will also play a new character - Spartan Kai-125 - described as "courageous and curious — and also deadly."
No projected premiere date for Halo has been announced.
