'Revenge': James Tupper replaces Marc Blucas in ABC drama

We have to admit, when "Buffy" star Marc Blucas was cast as Emily Van Camp's father in the upcoming ABC drama "Revenge," we went, "huh?" and immediately checked birthdays and did a little math.

It actually worked out okay, because in the pilot episode, Blucas was seen mostly in flashbacks to Van Camp's character's childhood.

But with Blucas committed to USA's "Necessary Roughness," ABC has cast a replacement with a couple of years on him to play daddy dearest. TVLine reports that "Men in Trees" star James Tupper will be replacing Blucas.

The role is a recurring guest spot, and Tupper is expected to appear in several flashbacks throughout the series -- though there's no word on whether he'll enter the modern day Hamptons setting of the new show.

"Revenge" premieres on Wednesday, Sept 21, at 10 p.m. on ABC.
