Wright, who won a Tony Award in 1994 for his performance in Angels in America: Perestroika and was Tony-nominated in 2002 for Topdog/Underdog, will join the HBO drama pilot "Westworld."
The cast of "Westworld" also includes Oscar winner Anthony Hopkins (Equus), Evan Rachel Wood, Rodrigo Santoro, Shannon Woodward, Ingrid Bolsø Berdal, Angela Sarafyan and Simon Quarterman.
The project — from J.J. Abrams' Bad Robot, "Person Of Interest" creator Jonathan Nolan, writer Lisa Joy, producer Jerry Weintraub and Warner Bros. TV — is inspired by Michael Crichton's 1973 sci-fi movie of the same name set at an amusement park.
McShane, who was seen on Broadway in The Homecoming and The Promise, has been cast in Dan Pritzker's biopic "Bolden," featuring a score composed by Grammy winner Wynton Marsalis (After Midnight). Also in the cast are Nelsan Ellis and Gary Carr, who stars as musician Buddy Bolden.
Pace, who was seen on Broadway in The Normal Heart, has been cast in the sci-fi thriller "Prisoner Of War," which also features Bérénice Marlohe.
Joe Miale will direct "Prisoner Of War," which tells the story of an American soldier and a French foreign aid worker who "team up in Africa amid humankind's last stand against a cataclysmic alien invasion."
"Prisoner Of War," set to begin filming in September in South Africa, is produced by Brian Kavanaugh-Jones, Rory Aitken and Ben Pugh and James Harris. Zev Foreman and Nicolas Chartier are producing for Voltage, and Mark Lane is co-producing for Tea Shop & Film.
