While NBC has not officially canceled the series, the decision has been made to put Heroes: Origins on hold, according to The Hollywood Reporter. The Heroes spin-off was slated to run for six episodes, during the midseason hiatus for for regular series. Well-known filmmakers such as Kevin Smith and Eli Roth had been tapped to write and direct their own episodes.

Some cite that a potential writers’ strike may be a major factor in NBC’s decision to halt the spin-off, given the budgetary concerns. Others believe that the decline in ratings for Heroes in general could also be to blame.
