Billy Bob Thronton, Jack Black, Dan Aykroyd, John's sister Joan, along with family and friends joined the crowd for the unveiling. Some even spoke on John's behalf.
Joan, who has co starred with John in numerous productions (Say Anything..., Grosse Point Blank, War, Inc, to name a few) led in a presentation speech that spoke of laughs and admiration for her kid brother.
"He's a cross between "It's a Wonderful Life, Dr. Strangelove and It's a Charlie Brown Christmas," she said.
Later that evening, while visiting on Jimmy Kimmel Live! Mr. Cusack said: "My star is right next to the singing cowboy Gene Autry, which is pretty cool, right?"
