If you see a grisly-looking, bearded guy getting the VIP treatment on Capitol Hill Thursday, don't be alarmed: It's most likely actor Kevin Kline, who'll be lobbying on behalf of the Juvenile Diabetes Research Foundation.

Kline is scheduled to meet with Sens. Byron Dorgan (D-N.D.), Frank Lautenberg (D-N.J.), and Rep. Chris Van Hollen (D-Md.).

The typically clean-shaven actor is best known for playing a fictional president in the political comedy "Dave," but his latest Washington-themed flick required a different look altogether.  

Kline will appear on the big screen later this year as President Abraham Lincoln's Secretary of War, Edwin Stanton, in a film about Lincoln's assassination being directed by Robert Redford. Titled "The Conspirator," Kline stars alongside Robin Wright Penn and James McAvoy.
