I think part of the problem was that they hired a
comedian who does impersonations. "Impersonations" aren't the same as a real actor believably
embodying person. Hammond has the accent and physical mannerisms and through all the hair & makeup the look, but he doesn't have the skills to believably act & embody the
essence of the real Colonel. Thus, he's coming out creepy under the hair, makeup & accent. An impersonation is always what it is, an
obviously superficial copy. Daniel Day Lewis embodied Abraham Lincoln when he did that role. We believed him as Lincoln. KFC can't afford Day Lewis, (nor would DDL want to do it,
) but surely they could have found a no-name
real actor who could have really acted and embodied the Colonel.
OR for the amount of money they must have paid Hammond, they could have done the special effects that Natalie Cole did with inserted actual nostalgic, filmed footage of her father Nat King Cole, in her
Unforgettable music video, only inserting real, old commercial footage of the real Colonel into a new "nostalgic" commercial.
Even the Snickers commercials use actual old footage from old TV shows and inserts them into a modern commercial. Like the Brady Bunch Snickers commercial with "Marcia" needing to eat a Snickers bar.
