HBO’s still-unnamed, long-planned 1970s rock ‘n’ roll drama pilot, set against the backdrop of New York’s emerging punk scene, is adding a couple more band members.

Max Casella (“The Sopranos”) and Jack Quaid (“The Hunger Games” movies) join the cast as music executives Julian “Julie” Silver and Clark Morelle respectively. While the hot-headed Jules struggles to stay hip and relevant, the younger Clark is just trying to get a foothold in this competitive, fast-paced world.

The project, which is scheduled to begin lensing this summer, stars Bobby Cannavale as Richie Finestra, the founder and president of a top-tier record label who is dealing with a crisis of character. Olivia Wilde plays his former actress-model wife and Juno Temple plays a manipulative, ambitious assistant at the record label.

“Boardwalk Empire’s” Terence Winter and “Breaking Bad’s” George Mastras co-wrote the script, which has been in development for a couple years. Winter’s “Boardwalk” and “The Wolf of Wall Street” collaborator Martin Scorsese will direct the pilot.

Adding some extra authenticity to the project is Mick Jagger, who is exec producing with his Jagged Films partner Victoria Pearman, as well as Scorsese, Mastras, Winter, Emma Tillinger Koskoff and Rick Yorn. Mastras would serve as showrunner if the pilot goes to series.

Casella, whose projects include the upcoming 1980s thriller “Heat,” is repped by Innovative Artists and Evolution Entertainment. Quaid, who appears in the upcoming Courteney Cox-directed “Just Before I Go,” is repped by UTA and Anonymous Content.
