The 1970s, a limited series musical Maroon 5 singer Adam Levine was going to produce for NBC, is not moving forward at the network. A pilot hadn’t even been filmed yet.

The project had been at NBC since August 2014 and came from Levine’s 222 Productions, Boardwalk Entertainment Group and Sony Pictures Television. According to The Hollywood Reporter, the 10-hour series was going to focus on the music executives and artists who helped make the best music of the ‘70s.

Sources for THR said that producers were trying to get Hayden Christensen and Kelsey Grammer for two of the major leads. They went back to NBC to see if this actors would get the network to give the show a straight-to-series order instead of just a pilot presentation. NBC balked and ultimately decided to scrap the entire idea.

NBC might have also felt that the show wouldn’t succeed, especially with Martin Scorsese’s Vinyl about to launch on HBO. The network also recently scrapped a Coach reboot after a pilot was filmed. NBC also failed with the expensive two-season musical series SMASH, so that makes one wonder why the producers would think NBC was the right place for this project in the first place.

Levine is currently a coach on NBC’s The Voice.
