1. - James Dean, Rebel Without A Cause, 1955. John had beaten Jimmy to Broadway's production of Tea and  Sympathy two years earlier - plus, The Cobweb movie, 1955.. Following Dean's death, Kerr inherited Jimmy's lead in the TVersion of  The Corn In Green.

2. - Dennis Hopper, Giant, 1955.

3. - Anthony Perkins, Friendly Persuasion, 1956.  Making "mistakes on roles" is among the reasons Kerr quit Hollywood and became a trial lawyer in the 70s.  He turned down this ex-Capra project for a three-picture MGM deal.  "In hindsight, I'd rather have been in a movie with Gary Cooper, directed by William Wyler, then to have been in Gaby and The Vintage at MGM."

4. - James Stewart, The Spirit of St. Louis, 1957.  Following James Dean's  tragic death, Kerr was next choice to fly the Atlantic single-handed.  He refused as he did not approve of Charles Lindberg's pro-Hitler stand during WWII. Director Billy Wilder went with the genuine Hollywood flier, although Jimmy Stewart was 20 years too old  - The Old Man and the Sky! And Warners lost $6m. (Way back in the Stewart family tree is a John Kerr Stewart).
