Keleghan's best-known roles have been film industry CEO Alan Roy on Made in Canada, low-IQ news anchor Jim Walcott on The Newsroom, and lonely, forgotten, deluded Ranger Gord on The Red Green Show. He also had a role in the Canadian film Ginger Snaps. Non-Canadians will more likely recognize Keleghan as one of two actors who played George Costanza's archnemesis Lloyd Braun on Seinfeld.
Peter Keleghan also voices Scaredy Bat, a character in the series Ruby Gloom.
