Whitford reflected on starring as presidential aide Josh Lyman on the show, joking that creator Aaron Sorkin's commitment to write nearly every episode of the early seasons seemed daunting.
"That show was such, again, you've got a guy who... was allowed to be the brilliant freak that he is and pull off something that initially seemed insane, let alone write every f**king episode," he joked to Collider.
Whitford further expressed his amazement at The West Wing: "I mean it's still, to me, the most amazing thing I've ever seen in show business, was [for Sorkin] to write 22 of those for four years, because they were complicated.
"It was beyond, as a creative experience, was beyond my highest expectations and for it to be in an arena that, at that particular time and that I've always felt and that I continue to feel is an urgent, fascinating arena... it was a really good gig."
West Wing producer John Wells recently spoke about how much television has changed since the series premiere in 1999 by insisting that the political drama would never air today.
The West Wing aired for seven seasons, earning 26 Emmy Awards and three Golden Globes.
