NBC is putting the brakes on Heroes: Origins -- and the possibility of a strike contributed to the decision, according to Variety.

The network has indefinitely shelved production on the planned six-episode spinoff of its Monday hit series -- which had attracted heavy hitters such as Eli Roth, Kevin Smith and Michael Dougherty (Superman Returns) -- was set to unfurl later this season while Heroes was on hiatus.

Now NBC has decided to not move forward with the production, at least for now.

NBC Universal entertainment co-chairs Ben Silverman and Marc Graboff didn't want to move forward with the project given the financial uncertainties of a possible WGA work stoppage.

Insiders cautioned that Heroes: Origins isn't completely dead and could very well be revived at a later date, perhaps as soon as next season.
