David Selby, at an exact 6ft 2 (188 cm), commands attention with his towering stature that has defined his imposing presence across television and film. His height perfectly suited the menacing vampire Quentin Collins on the cult 1960s series Dark Shadows, enhancing the character's supernatural threat. Selby's tall frame brought gravitas to the ruthless Richard Channing on the 1980s soap Falcon Crest, as well as key roles in Flamingo Road (1981–82) and the epic feature Raise the Titanic (1980).
In a 1969 bio, Selby proudly stated, "I am six feet and two inches tall," highlighting how his 6ft 2 height has been central to his commanding image and career highlights.
