With the competition gearing up to go back on the air sans writers David Letterman hopes to return soon with his own personal interim agreement with the Writers Guild of America. How can he do that? Because Letterman's company Worldwide Pants owns his show and its companion, The Late, Late Show With Craig Ferguson. The Writers Guild on Saturday announced plans to begin negotiating individually with companies, after the umbrella organization negotiating on behalf of networks and studios broke off talks on Dec. 7. The Guild already has granted one-time waivers to allow some awards shows to be produced with striking writers.
