Thin Ice (2011 film)

Thin Ice formerly The Convincer is a 2011 comedydrama film starring Greg Kinnear, Alan Arkin and Billy Crudup, directed by Jill Sprecher.

Gorvy also has an old violin. A man named Dahl, an appraiser from Chicago who has a shop filled with musical instruments, examines the violin and says it is somewhat rare and actually worth 25,000. Complications arise when Mickeys plan to steal the instrument is discovered by a smalltime excon named Randy Kinney, who not only will not leave Mickey alone, but turns violent and bludgeons one of Gorvys neighbors to death.Continued inspection and research on the violin values it at forty times the original estimate. Mickey now is in possession of a milliondollar instrument, but Randy wants his share and threatens to kill Mickey if he does not get it. Mickey thinks he can still come out of this all right, until he discovers that he is in way over his head. ........
