TV's top-rated show will ring in the holidays with a guest star-filled episode on December 15.

Ralph Waite will return on that date as Gibbs's father, while TV Guide Magazine reports a pair of other semi-big names have signed on for roles on the NCIS installment titled "Faith."

Corey Reynolds (The Closer's Sgt. David Gabriel, pictured) will play a naval chaplain that assists the team with its investigation.

Meanwhile, Joe Regalbuto (best known as Frank Fontana on Murphy Brown) will play a reverend whose son turns up dead.

On other casting news, Robert Wagner will show up as Tony's father on NCIS' 150th episode.
