Sylvio works for a debt-collection company, spending his days shredding paperwork and fielding follow-up payment calls. At night, he glumly eats his TV dinner and films hand-puppet shows featuring a balding, middle-aged salesman. A chance appearance on a Baltimore public-access talk show, where he breaks things on the set, turns him into an unlikely local celebrity. Also, he is an ape who wears sunglasses. Directors Kentucker Audley and Albert Birney take a one-joke premise and wring every ounce of mumble-goof absurdity possible from it, as well as some choice po-faced digs at showbiz phoniness and unexpected poignancy. If SXSW was smart, they'd announce a "surprise screening" of Kong: Skull Island and show this in that slot instead.
