Remember the days:
6’ 1½” Cary Grant
6’ 4” John Wayne
6’ 2” Charlton Heston
6’ 3” Gregory Peck
6’ 1” Henry Fonda
6’ 1” Clark Gable
6’ 3” James Stewart
Might be that Hollywood is more willing to work with shorties these days. There’ve always been tall actors, but there’s also always been shorties like Mickey Rooney, and Peter Lorre (both 5’3”).
