Actor Bill McKinney, best known for appearing in Deliverance's famous "squeal like a pig" scene as the Mountain Man rapist, has died at the age of 80.

An avid smoker for 25 years, McKinney succumbed to esophageal cancer, according to a statement posted Thursday on his Facebook page.

"Today our dear Bill McKinney passed away at Valley Presbyterian Hospice," read the statement. "He was 80 and still strong enough to have filmed a Dorito's commercial 2 weeks prior to his passing, and he continued to work on his biography with his writing partner. Hopefully 2012 will bring a publisher for the wild ride his life was."

In addition to his role in 1972's Deliverance, McKinney appeared in dozens of films (including seven of Clint Eastwood's projects) and on TV shows like Walker, Texas Ranger and Baywatch.

McKinney is survived by a son, Clinton, and several ex-wives.
