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.

Selleck also has developed an impressive acting resume in the television movie genre including his popular “Jesse Stone” movies. Selleck will next be seen in the fourth installment of this franchise called “Jesse Stone: Sea Change,” on May 22nd. Television movies have also allowed him to explore his interest in Westerns, with roles in the similar-themed “Monte Walsh,” “Crossfire Trail,” “Last Stand at Saber River,” “The Sacketts” and “The Shadow Riders,” among others. Selleck earned strong reviews for his performance as General Dwight Eisenhower in the television movie “Ike: Countdown to D-Day,” and starred in others, including “Twelve Mile Road.”

NBC renewed “Las Vegas” (Fridays, 9-10 p.m. ET) for a fifth high-rolling season in February.
