EXCLUSIVE UPDATED: The Sopranos alum Michael Imperioli and former Heroes star Adrian Pasdar round out the lead cast of Doug Ellin’s HBO pilot 40. The two join previously cast Ed Burns and Michael Rapaport in the single-camera ensemble comedy, which revolves around four lifelong friends who help each other navigate life at 40, which isn’t all they expected it to be. Burns plays a married guy and a father who used to work at Bear Stearns making more than $2 million a year but has now been out of work for almost a year. Rapaport plays another friend, also married, who is described as a neurotic everyman. Imperioli plays a single guy, a hustler who is shameless when it comes to self-promotion. Pasdar plays the fourth of the buddies, a Wall Street millionaire. Also cast in the pilot is Susan Misner, who guest stars in the premiere of CBS’ Person of Interest tonight. She will play Burns’ character’s wife. This marks the return to HBO of UTA-repped Imperioli, who won an Emmy for his turn on The Sopranos. He most recently starred in the ABC drama Detroit 1-8-7. While also known mostly for his dramatic roles, Pasdar has been dabbling in comedy. Last season, he starred in NBC’s untitled Kari Lizer half-hour pilot. The actor, repped by ICM and manager Will Flaherty, has been recurring on the ABC Family drama The Lying Game.
