"They're both ensemble shows [ER and The West Wing], they're both very fast-paced, and they're both these big animals -- every week, there's a lot going on," she says. "So they don't feel that different. ... I enjoy the kind of language- and intellect-based world of 'The West Wing,' where people are discussing ideas. - Laura Innes

Lawrence Lessig, a Stanford University professor who is a leading American intellectual property scholar known as "the Elvis of cyber law," has now achieved a measure of fame among fans of "The West Wing." In Wednesday night's episode, "The Wake Up Call," Christopher Lloyd ("Back to the Future") made a guest appearance as Prof. Lawrence Lessig, a Harvard University legal expert enlisted to explain particulars of the Constitution to members of a delegation from Belarus as they write a new, democratic constitution. The character is based on the screenwriter Josh Singer's real-life mentor, Professor Lessig, with whom he studied contract law at Harvard in 1997. "It was one of my first courses, and he was unbelievable," Mr. Singer said. "He was a rock star." In preparing for the episode, Mr. Singer also remembered that Professor Lessig had been asked, in his capacity as co-director of the Center for the Study of Constitutionalism in Eastern Europe, to help work on the Georgian constitution. "I called him up and asked him to tell me more about what had happened," Mr. Singer said. "On the set, we replicated what they had done." No word yet on the real-life professor's feeling about the episode, though Mr. Singer said that after reading the script and giving formal approval, his mentor "seemed to be pretty thrilled."

On "The West Wing," Sheen plays a president who finds ways to do his job despite multiple sclerosis. A University of California consultant has advised Sheen on how to play the struggle with the disease."What she told me was to be subtle. I can have many ups and downs," he said.
Subtle and optimistic. "(MS) patients see the light at the end of the tunnel," Sheen said.
Sheen isn't an official spokesman for MS because, unlike his character, he doesn't have the disease.
