What's the big deal? They are under contract to NBC.

If I were those "stars" and had moved on to bigger and better things, I wouldn't want to appear on a dying show anyway.

Dickish move.

Great. Now I hate NBC too.

Gift shop Girl! Franklyn!

The beef could also be between NBC and ABC heads Ben Silverman and Steve McPherson, who have been trading barbs ever since Silverman took the job at the expense of McPherson's friend Kevin Reilly. Still, this is pathetic and completely unprofessional on NBC's part, and particularly rich given the fact that NBC's prez owns a stake in one of ABC's shows, "Ugly Betty". Luckily if industry insiders are right, we might not have to worry about Silvermania much longer.

This is odd considering the NBC/CW crossover with the two Gossip Girl stars appearing on 30 Rock. Considering all the different entities involved in that, it's amazing something like this is happening. I could see why NBC would bar stars from appearing on Scrubs on ABC if ABC/Disney had actually stolen the show from NBC, but NBC gave it up so what's the harm? It could only be seen as a gesture of goodwill, but perhaps the beef isn't with ABC but for Bill Lawrence, as you said, who hasn't been silent on his displeasure with NBC's handling of Scrubs. Lawrence perhaps burned a bridge that can't be repaired. And how could they be filming the series finale already?? Doesn't ABC have the option to bring it back if ratings take a tick up?

Their decision is short-sighted. NBC let Kyle Chandler appear on ABC's Grey's Anatomy despite being on an NBC show at the time. His role was a small but much talked about one too. If anything, it might have attracted new viewers to his NBC show, since it has low ratings.

NBC = Nothing But Crap

Ben Silverman needs to be shitcanned immediately.

At least they had the sense to get their shows back in the iTunes Store.

I don't understand, can someone help me out? How does having Heroes and Chuck stars appear in other shows hurt NBC? Is NBC afraid that a Heroes fan might follow Masi Oka over to his guest spot on ABC and then fall in love with all of the ABC programming and never come back? It seems more likely that it would create more awareness of Heroes and Chuck.
