Will Gerald McRaney join ‘NCIS: Los Angeles’ full time?

Matt Roush: By my count, Gerald McRaney has appeared on “NCIS: LA” as retired Navy Admiral Hollace Kilbride at least five times over the years, so he’s clearly a favored recurring guest star.

But for now that seems to be the extent of his involvement. There’s no show he doesn’t make better, so I imagine he’d be welcomed back any time.

I haven’t seen anything to suggest that the producers are looking to expand the core cast, though, so you’re probably going to have to settle for enjoying him next time he returns.

(I agree, though, that an episode centered on Hollace and Hetty would be great.)

Question: Stephen Colbert seems to have a week’s worth of reruns every other week. Does he have a contract that calls for this? — Paul

Roush: I don’t begrudge these shows or their stars occasional time off, because the schedule is grueling.

But I admit I was also thrown that “The Late Show With Stephen Colbert” had scheduled time off during a week when a Democratic debate was happening — which is typically a ripe occasion for a live broadcast.

However, this was his first break since the Labor Day hiatus, and if that seems lazy to you, so be it.
