“Development was really starting to heat up, And it appears like I may be writing multiple pilots for NBC so that wasn’t leaving a ton of room for ‘Heroes,’ unfortunately,” said Fuller to Ain’t It Cool News when asked to verify the claims from their previous anonymous source. “We crafted some really great arcs for the season that I’m excited to see come to fruition. I love that cast dearly and am sad to go, but the plate — she was over-flowing.”
Fuller recently returned to Heroes, where he was a writer-producer for the first season before leaving to concentrate on Pushing Daisies. Once that show was cancelled, he then return to the super-powered fold last December, and is often cited as the reason for the show’s creative turnaround near the end of the third volume. Heroes is currently in production of its fourth season, due to air in the autumn.
