Jamey Sheridan has been cast in the much-anticipated role of Tim's father on NCIS.

Admiral John McGee will make his debut on the CBS drama sometime in late March.

We will finally meet McGee's father in an illuminating episode titled “Squall.”

“Jamey Sheridan’s recent work on Homeland [as Vice President Walden] just reinforced what a terrific actor he is,” NCIS show runner and executive producer Gary Glasberg told TV Line of the casting.

“The role of McGee’s father is complex and layered with some real surprises thrown in," he adds. "We can’t wait to see what Jamey does with it and how he plays opposite Sean Murray.”

The most interesting part? Glasberg promises McGee's father “will be part of what leads us into our final arc,” which often provides the year's most complex and thought-provoking episodes.

Sheridan recently appeared on Homeland Season 2, and on Arrow (as Oliver’s doomed dad), but is likely best known as a series regular for years on NBC's Law & Order: Criminal Intent.

What do you think? Good choice for the part? And what role do you expect he'll play?
