(written from a Production point of view)
Lisabeth Mary Shatner (born 6 June 1961; age 51) is the middle daughter of William Shatner and the older sister of Melanie and younger sister of Leslie Shatner. Together letters from the names of the three sisters were used to make up the name Mr. Lemli. She is also co-writer (with her father) of Captain's Log: William Shatner's Personal Account of the Making of Star Trek V: The Final Frontier.
Besides Star Trek, Lisabeth appeared alongside her father in a 1986 episode of T.J. Hooker entitled "Partners in Death" and a 1996 episode of TekWar entitled "Betrayel." The latter also guest-starred her sister Melanie, and was directed by their father.
Shatner is currently married to makeup/effects artist Andy Clement.
