Alan Arkin
Although official, the live-action film "Inspector Clouseau" (1968) starring Alan Arkin as Clouseau, is generally not considered by fans to be part of the series canon, since it involved neither Sellers nor Edwards. However, some elements of Arkin's performance and costuming of Clouseau were retained when Peter Sellers resumed the role for "Return" in 1975. Despite speculation, Alan Arkin does not appear in "Trail of the Pink Panther."
