NBC has given the axe to Heroes co-exec producers Jesse Alexander and Jeph Loeb, according to Variety.
Both writer-producers had been with the show since its first season and were known to have led the day-to-day production operation under the direction of creator/exec producer Tim Kring.
Heroes, produced by Universal Media Studios, has struggled in the ratings its third season. It's understood that Alexander and Loeb were let go because of Peacock execs' frustration with the creative direction of the show. The show is also said to have been grappling with hefty budget overruns this season, that are going well beyond its already sizable $4 million per-segment pricetag.
