Earlier today, Michael Weatherly spoke on his beloved NCIS character of Tony.

Now, following a CBS casting announcement, the actor probably has a lot more to say: Robert Wagner will portray Tony's father on the 150th episode of TV's top-rated series. The milestone installment will air in January.

On the small screen, Wagner most recently appeared on five episodes of Two and a Half Men in 2007-2008.

In a coincidental twist, Weatherly played Wagner in the 2004 TV movie The Mystery of Natalie Wood.
