Who is Scott Bakula ?

Scott Stewart Bakula (born October 9, 1954) is an American actor who played leading roles in two science fiction television series: "Quantum Leap" and "Star Trek: Enterprise". He also co-starred with Maria Bello in the short-lived CBS television series "Mr. & Mrs. Smith" (which bore little or no relation to the 2005 motion picture of the same title), and had a recurring role in the sitcom Murphy Brown.

Bakula was born in St. Louis, MO, and graduated from Kirkwood High School in Kirkwood, MO in 1973. During high school, he was active in soccer, tennis, and theatre. Also during high school, he had the lead roles in 'Godspell' and 'Joseph and the Amazing Technicolor Dreamcoat' at First Presbyterian Church in Kirkwood. He also played Tevye in an Independent Theatre Production of 'Fiddler on the Roof' at Kirkwood High. Bakula attended college at the University of Kansas, studying law, until his junior year. He was a member of Phi Gamma Delta while attending the University. Bakula then left to pursue acting, having been cast in the leading role of 'Godspell'. After that show completed its run, he moved to New York and acted in Broadway shows such as 'Joseph and the Amazing Technicolor Dreamcoat' and 'Fiddler on the Roof'.

(...from Wikipedia)

Quantum Leap is an American science fiction television series that ran for 96 episodes from March 1989 to May 1993 on the NBC network.

The plot involved scientist Sam Beckett (Scott Bakula) leaping to various points in time, usually constrained within the period of his own lifetime.

The show, which crosses a number of themes, including science fiction, family drama, comedy, social commentary, and nostalgia, won a broad range of fans. Sam occasionally has minor encounters with celebrities such as Buddy Holly and Michael Jackson as youths, helping to inspire their eventual fame (an example of a type of predestination paradox).

By the very nature of the show's premise, the cast of characters was ever changing, always different -- but there were some constants:

• Scott Bakula as Dr. Sam Beckett


• Dean Stockwell as Admiral Al Calavicci


• Deborah Pratt as Ziggy (Ziggy appeared starting in 1989)
