The Writers Guild of America, while still on strike, made an exception and reached an agreement with David Letterman and CBS, enabling the writing staff to continue its work on “Late Show with David Letterman” and “Late Late Show with Craig Ferguson” starting next week.

Letterman’s production company Worldwide Pants reached an independent agreement with the Writers Guild of America, but this only includes the two shows. The rest of the CBS productions are to return on Wednesday, according to the network, but without writers.

It appears that Letterman and Ferguson’s show will also become the only productions to attract celebrity guests, considering that the TV and movie stars refused to go on other shows, such as “The Ellen DeGeneres Show” and “Last Call with Carson Daly”, out of solidarity with the writers’ strike.

No details have been disclosed on the next week show, including the guests, but the two productions promise to attract most viewers, considering they are the only ones to make peace with the writers. Other shows also announced their comeback next week, “The Daily Show” and “The Colbert Report’, “The Tonight Show with Jay Leno” and “Late Night with Conan O’Brien”, but without their writing staff.

The recent deal has been on Letterman’s mind for some time now, but nobody thought it was likely to happen. Letterman issued a statement, following the agreement: “I am grateful to the WGA for granting us this agreement. We’re happy to be going back to work, and particularly pleased to be doing it with our writers. This is not a solution to the strike, which unfortunately continues to disrupt the lives of thousands. But I hope it will be seen as a step in the right direction.”

What exactly made the Writers Guild of America make such an exception, we don’t know, but it will certainly put a great deal of pressure on other networks to do the same. The WGA said in a statement: “Today's agreement dramatically illustrates that the Writers Guild wants to put people back to work, and that when a company comes to the table prepared to negotiate seriously, a fair and reasonable deal can be reached quickly."
