I agree whole heartedly with the disgust shared by Sam and Matty. Recasting these actors should be a crime. But, above all recasting Bill Murray is a down right sin. This, is the William James Murray memorial list.
Dr. Peter Venkman (Ghostbusters) ... Dr. Peter Venkman
Bob Harris (Lost in Translation) ... Dr. Raymond Stantz
Herman Blume (Rushmore) ... Dr. Egon Spengler
John Winger (Stripes) ... Winston Zeddmore
Bunny Breckinridge (Ed Wood) ... Dana Barrett
Carl Spackler (Caddyshack) ... Louis Tully
Raleigh St. Claire (The Royal Tenanbaums) ... Janine Melnitz
Ernie McCracken (Kingpin) ... Walter Peck
Bill Murray (Coffee & Cigarettes) ... Mayor
Bill Murray the K (The Rutles: All you need is Cash) ... Male Student
Bob Wiley (What about Bob?) ... Female Student
Dr. Hunter S. Thompson (Where the Buffalo Roam) ... Gozer
Tripper Harrison (Meatballs) ... Gozer (voice) (uncredited)
Phil Connors (Groundhog Day) ... Zuul / Slimer (voice) (uncredited)
Couldn't you envision Bunny Breckinridge and Peter Venkman finally falling in love....Or Carl Spackler asking "okay, who brought the dog?".....Or Bill Murray as mayor. We can start as Mayor and work our way to presidency later.
