Variety says there was a big shakeup behind the scenes of NBC's "Heroes" on Sunday as writers/co-executive producers Jesse Alexander and Jeph Loeb were fired.
The duo 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/executive 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 NBC executives' frustration with the creative direction of the show.
The trade added that the show is also said to have been dealing with hefty budget overruns this season that are going well beyond its already sizable $4 million per-episode pricetag.
