CBS and FOX studios have threatened to file lawsuits against their top show runners if they do not immediately go back to work and complete their non-writing duties. The news comes as people like Damon Lindelof and Carlton Cuse ("Lost"), Marc Cherry ("Desperate Housewives"), Shonda Rhimes ("Grey\'s Anatomy") and many others joined their writers on the picket lines on Wednesday.

Although show runners are essentially writers and creators of their respective series they also own production companies as part of deals with studios and their role is to oversee the production and perform a number of non-writing duties on the set.

The industry\'s top show runners however decided to completely walk out of their productions and join writers in the picket lines.

TV\'s top showrunners rallied in front of Disney studios on Wednesday to send a clear message they are "united in the fight against corporate greed."

The show runners also said if only one lawsuit is filed none of them will return to work.

They are asking the studios to come back to the negotiating table. If so, they would be willing to complete production on several already written episodes.

The studios however claim the show runners have breached their contracts and already caused studios and networks irreparable monetary damage.
