How can you be understated and a giant at the same time? Gregory Peck had these qualities. The subtext never failed to reveal itself in his performances. Always assured and in the moment.
No one will ever forget his performance as Atticus Finch in To Kill a Mockingbird, not to mention his performance in Spellbound and much later in the Boys from Brazil.
There are too many to mention Cape Fear, Guns of Navarone, The Omen, Moby Dick.
