David Letterman, Jay Leno and Conan O'Brien could be back on TV before Hollywood writers end their strike, Variety reports. Writers are striking over how much they should be compensated for content distributed over the Internet and on DVDs, but producers for the three late night shows are in secret talks to bring back their own scribes before the strike ends. That could be a serious blow to the writers' cause. So far, late-night reruns are the only sign for most television viewers that anything's going on at all. Producers won't run out of sitcom and drama scripts until January.
