O'Brien, like many "SNL" writers, occasionally appeared as an extra in sketches; his most notable appearance was as a doorman in a sketch in which Tom Hanks was inducted into the SNL "Five-Timers Club" for hosting his fifth episode. O'Brien returned to host the show in 2001 during its 26th season. O'Brien and Robert Smigel wrote the television pilot for "Lookwell" starring Adam West, which aired on NBC in 1991. The pilot never went to series, but it became a cult hit. It was later screened at "The Other Network", a festival of unaired TV pilots produced by Un-Cabaret; it featured an extended interview with O'Brien and was rerun in 2002 on the Trio network.
