"The West Wing" cast reunites for walk-and-talk video

(CBS News) "The West Wing" characters are back doing creator Aaron Sorkin's signature walk and talk through the White House hallways.

Some of the members of the series reunited for a new Funny or Die video that promotes American fitness through some fast talking and walking.

The video stars Allison Janney, Dule Hill, Joshua Malina, Melissa Ftizgerald, William Duffy and Martin Sheen, all reprising their "West Wing" personas as they walk through the halls talking about a health initiative they want the President to approve, touting the benefits of walking.

While the banter reads like the show's classic Sorkin dialogue, the Oscar winner did not write the script for the two-minute clip.

The video was produced for Everbody Walk!, the national campaign designed to get people up and moving for just a few minutes every day.

None of the actors'  "West Wing" characters' names are actually used, though President Barlett, a.k.a. Sheen, does give Mrs. Landingham a shout-out.
