He already had a few TV credits to his name at the time, the
first being an episode of Armstrong Circle Theatre in 1959
on CBS, a 31- year – old Robert Duvall introduced himself
to many audiences in 1962 with a silent and inscrutable 
stare with his film debut as Boo Radley, the harmless
oddball neighbor in the Robert Mulligan-directed, Horton
Foote-written adaptation of Harper Lee’s To Kill a
Mockingbird.
 

 

Robert Selden Duvall will be 94 on January
5, 2025.
