<p>It wasn’t a conflict with Sheen but rather with the writers and the direction of the show.</p>
<p>Initially, the show was supposed to focus primarily on the West Wing staffers, with the president as a recurring but relatively minor character. (In the pilot, he is seen only in the last five minutes.) The creators of the show wanted a very recognizable face in one of the leading roles. Thus, they hired Rob Lowe, for quite a lot of money, and gave him first billing. </p>
<p>But the show quickly evolved into something different from what had been envisioned. The president, who was initially supposed to appear in only a few episodes a year, became a leading character, and the roles of the staffers evolved into supporting roles in an ensemble show. Rob Lowe found himself being one of many actors in a large ensemble – not the job that he was hired for. He stuck around for three and a half years, but he was never happy, and as time went on, there seemed to be less and less for his character to do. So he left, which may have been a mistake because his next two attempts at TV series bombed, and he is now playing a supporting role in a large ensemble – on Brothers and Sisters. But at least this time he knew what he was getting into.</p>
<p>Personally, I also wonder whether Rob Lowe was ever comfortable working with the other actors on The West Wing. Except for Sheen, none of the other regulars on that show was a recognizable star, although all were experienced and skilled actors. I have heard that several of the regulars, including John Spencer, Allison Janney, Bradley Whitford, and Richard Schiff, became very close friends, but you never hear about Lowe being part of that little group. Also, Lowe’s attitude about the whole job had to have been different from that of the others. When Bradley Whitford accepted the Emmy he won for the second season, he thanked Aaron Sorkin, the show’s principal writer, for “the role of a lifetime.” I expect that Spencer, Janney, and Schiff probably thought about their roles in the same way. But Rob Lowe didn’t. That would have set him apart.</p>
<p>Regardless of the politics, in my opinion it was a shame that Rob Lowe left. Sam Seaborn was a wonderful charcacter, with lots of interesting shadings. I missed him when he was gone.</p>
