No Sunday Night Football this week on NBC due to the World Series (Go Tigers! Stupid Yankees!). So, in its place the network will be airing a mini Heroes marathon.
The marathon will begin after Football Night in America. The three episodes that will be airing are "Don't Look Back", "One Giant Leap" and "Collision". The pilot episode, "Genesis", will not air that night. On Monday Heroes will air in its normal time slot with a new episode.
Heroes has been one of the bright spots in a schedule featuring expensive dramas with poor ratings. Earlier this month the show was picked up for the entire season. I'm guessing that this marathon is to give viewers unfamiliar with the show a chance to see what it has.

Javier Grillo-Marxuach, a writer and
supervising producer for
Lost, is really expanding his horizons. On top of co-writing two episodes this season,
Orientation and
Collision, he also hosts a regular
Lost video podcast and regularly posts updates on
The Fuselage. He's also been writing an indie-comic called
The Middleman, which apparently got
him noticed by Marvel Comics. He's working on the
Super-Skrull miniseries, an old school villian who once
battled
The Fantastic Four,
Thor and
Captain Marvel. Grillo-Marxuach is re-working
Super-Skrull, to transform him from a villian to a hero. There will be four issues, starting in March.
Grillo-Marxuach said, "It's nice to do
The Middleman, which is my own thing, but it's really
cool, much in the same way as my work on Lost, that I get to be part of something much bigger."
