Adam Levine's 1970s Miniseries Scrapped by NBC

The 1970s was poised to explore the decade through the eyes of the music executives and artists who helped create some of the most influential music of the era.

Sources tell THR that Hayden Christensen and Kelsey Grammer were engaging to play the leads. Producers, insiders say, went back to NBC to see if the casting would get the network to go straight to series on the project, instead of the planned pilot presentation. Insiders say NBC toyed with the numbers but ultimately decided it didn't want to take the gamble and pulled the plug completely. Producers are said to be coming up with new ideas for a different music project.

The potential series hailed from Boardwalk Entertainment Group and was eyed as a 10-hour event series that was to feature contemporary stars re-recording classic '70s hits.
