While I was trying to find out the location where "Heroes" was filming, I stumbled upon an old article from Superherohype.com.
Jesse Alexander signs on
A former writer/co-executive producer of "Alias" and co-executive producer of "Lost" has signed a two-year deal with NBC to be a co-executive producer for "Heroes" if it goes to series.
Hollywood Reporter more in depth
Hollywoodreporter.com also has this story, although put a bit differently. The two-year deal is with NBC Universal Television studio. Jesse Alexander won an Emmy (along with 10 other people) for "Lost." Because of this discrepancy, the already asked question
Is this a full season or half season? remains 100% answered.
Here is a listing for Jesse Alexander at IMDb.com

PS - Anyone know where "Heroes" is being filmed? If so, please post it in "The Show" forum. Trust me, I'll see it.

Even if it is some studio number, that would be helpful. Also, how do I edit the hyperlink when posting links? The links are an eyesore in my post. :oops: :oops:
Edited for my own veiwing pleasure as well as yours hopefully!
