Oldboy (2013)
He first appeared watching Joe Doucett's 20-year hotel room imprisonment after being payed by Adrian Pryce to imprison Joe.

20 years later, he releases Joe and continues watching the prisoners. However, Joe came to Chaney and holds him hostage. He then puts cuts on Chaney's neck and spills salt on the wound to torture him into talking until he confesses that he was payed into imprisoning Joe but doesn't know Adrian's name. Joe then uses him as a human shield against the guards and then abandons Chaney to escape. Chaney then got upset to see his pal Marco has gotten killed by Joe.

Later on, Adrian tells them Marie's address and they attack her in revenge for what Joe did to them. Joe came to save her but they outnumber him and hold him towards a table. Chaney prepares to torture him with a straight razor but is given a call from Adrian to let Joe go. Chaney refuses to but only to be payed a bag of diamonds and he does let Joe go before him and his men leave.

After Adrian's death, Joe visited Chaney and paid him to lock him up in order to forget finding out that Marie is Joe's daughter. It is unknown what happens to Chaney after this but he possibly still runs the prison and has given up his grudge against Joe.
