As buzzed about a month ago, NBC has signed Emmy winner Tom Selleck ( Magnum, P.I.) to join the cast of NBC's Las Vegas this fall, playing "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 making the announcement, NBC also revealed that - as some form of baton-passing, I presume - James Caan will reprise his role of Ed Deline in the Season 5 premiere. It was announced earlier this year that Caan would be leaving Las Vegas after its fourth-season finale, but just when he thought he was out, they pulled him back in. (Little Pacino/ Godfather/Sonny Corleone reference for ya there.)
