I haven't seen this in a long time, but I recall that Blake was outstanding. His "George" became a reference point for all other versions. I should point out that I became a fan of Steinbeck's books after seeing this. I felt that Blake did great justice to the character. Blake is completely convincing as a guy who's been through a lot and carries the world on his shoulders, yet remains warm-hearted (probably because that's very much like the man himself). His ability to portray this type of character also probably accounts for his great success with his Baretta character, which I enjoyed when it first ran back in the 70s.
