Lon Chaney Sr., standing at exactly 5ft 7 (170.2 cm), was a legendary American horror actor whose average height was central to his transformative screen presence in silent films. His stature enabled extraordinary physical contortions and makeup artistry, allowing him to embody grotesque, larger-than-life characters like the disfigured Phantom in The Phantom of the Opera (1925) and the hunchbacked Quasimodo in The Hunchback of Notre Dame (1923). Known as the 'Man of a Thousand Faces,' Chaney's 5ft 7 frame supported iconic roles in The Unknown, Laugh, Clown, Laugh, The Unholy Three, He Who Gets Slapped, and The Penalty, redefining horror through sheer physical dedication.
