BRYAN FULLER QUITS HEROES!
-Can't focus on dying show and his development deal, at once.
From EW.com

Just as Heroes was gaining some creative momentum comes word of
another setback: Bryan Fuller has vacated his post as consulting
producer.


The acclaimed Pushing Daisies auteur tells me that he left to focus on
developing new projects for NBC, and not (as some have speculated) due
to creative differences with series creator Tim Kring.


"I'm crafting two pilots right now and it's a lot of work," admits
Fuller, who has an overall deal with NBC. "It was just too hard to
[juggle] Heroes and my development; something had to give."


Fuller's exit was first reported by Herc at Ain't It Cool News.


Fuller returned to Heroes last December, shortly after ABC dropped the
ax on Daisies. Many (yours truly included) credited him with the
show's end-of-season creative rebirth.
