"Reacher is 6'5" tall (1.96 m) with a 50-inch chest, and weighing between 220 and 250 pounds (100–115 kg). He has ice-blue eyes and dirty blond hair. He has very little body fat, and his muscular physique is completely natural (he reveals in Persuader that he has never been an exercise enthusiast). He is exceptionally strong, has a high stamina, but is not a good runner."

I don't know if Tom Cruise fits any of those things?

I always pictured Jack Reacher as someone like Raymond's brother Robert in "Everybody loves Raymond."
