NBC announced that Emmy Award winning Tom Selleck (Magnum, P.I.) will return to television series drama when he joins the starring cast of NBC's Las Vegas (Fridays, 9-10 p.m. ET) next season as a charismatic, self-made billionaire who is surrounded by an air of mystery when he becomes the new owner of the Montecito Resort & Casino.

In addition, James Caan, who has starred as Ed Deline, the Montecito's surveillance head for four years, will return to the series for one episode in its 2007-08 season premiere after announcing earlier this year that he would be departing the series after its 2007 season finale.

"We have been honored and blessed to have had an actor of the magnitude of James Caan for the last four years and we've come up with four aces as legendary icon Tom Selleck has agreed to join the cast," said executive producer Gary Scott Thompson.

The popular Selleck established himself as a major television star with his performance as affable private detective Thomas Magnum on the hit drama Magnum, P.I. from 1980-88. He eventually served as an executive producer of the series. At the same time, he began a successful feature-film career as he starred in 3 Men and a Baby, Runaway, High Road to China, Lassiter, Her Alibi, Mr. Baseball, Christopher Columbus: The Discovery, In & Out, Quigley Down Under,The Love Letter and the recent hit Meet the Robinsons, in which he voiced the character of Cornelius.

In addition, Selleck was a recurring regular on Friends as Monica's (Courtney Cox Arquette) boyfriend, in which he garnered an Emmy nomination, and recently guest-starred in four episodes of Boston Legal as Candice Bergen's ex-husband.

NBC renewed Las Vegas (Fridays, 9-10 p.m. ET) for a fifth high-rolling season in February. From Thompson -- the writer of the hit film The Fast and the Furious -- Las Vegas is a fast-paced, sexy drama that follows an elite Las Vegas surveillance team charged with maintaining the security of one of "Sin City's" largest resorts and casinos.
