David has been all over the place ... Since 1995, he's played the role of Harm Rabb in JAG, but the role that brought him to my attention was MacNamee in Clockwatchers, starring Lisa Kudrow, Alanna Ubach, Toni Collette, and Parker Posey, Patti Yasutake, Paul Dooley, and Kevin Cooney. In JAG, he appeared with Andrea Thompson of Babylon 5 fame.
