Gregory Peck starred in three of the best movies I have seen.
To kill a Mocking Bird was a movie based on the law and the court room. It still stands up well today.
Twelve O'Clock high was a thinking man's war movie. Peck changes a US squadron of bombers based in England . He eventually goes nuts though.
A Big Country is the thinking man's western. I couldn't do the movie justice so just watch it and enjoy it.
no gunfights though. Great cast!
