William R. Moses

Marian remarried in 1970 to the Republican Congressman Alphonzo E. Bell Jr. (1914–2004). Congressman Bell adopted Moses and his brothers Rick and Harry. He briefly attended Wesleyan University.

In 1988, Moses co-starred in the film Mystic Pizza with Julia Roberts. He then joined Raymond Burr in 17 Perry Mason TV movies from 1989–93, playing Ken Malansky, an attorney who worked with title character Mason as a private investigator (although in Moses' first appearance as Malansky, the character – then a law student – was defended by Mason on a murder charge). Moses continued the role in the four TV films produced after Burr's death in 1993, subtitled A Perry Mason Mystery (which aired until 1995 and starring Paul Sorvino and Hal Holbrook).

In 1992, Moses returned to soap operas, playing the recurring role of Keith Gray in 11 episodes of Melrose Place. In 1997, he played David Graysmark in the short-lived series Fame L.A.. He continued to appear in a number of films and TV movies including Double Exposure, Trial by Jury (both 1994), Hangman's Curse (2003), Christmas Child (2004), A Lover's Revenge (2005) (starring his former Perry Mason co-star Alexandra Paul), and as Jack Davis in nine of the Jane Doe series of TV films from 2005–2008.

Moses was married to actress Tracy Nelson from 1987 to 1997, with whom he has a daughter, actress Remington Elizabeth Moses (born 1992). In 2000 he married Sarah Moses.
