Ralph Richardson received his second and final Oscar nomination a posthumous one for portraying The Sixth Earl of Greystoke.
Ralph Richardson portrays the Grand Father of Tarzan. Richardson character and performance is that of a nice supportive old man. There really is nothing else to the role. It is a fairly standard stock role, and Richardson is just fine in it. He never has anything scenes that really requires anything more for him. He is simply just a likable old nice figure who is supportive to Tarzan.
Richardson is perfect in the role technically, I like his presence in the film, and it is a nice little performance. There is not single thing wrong with his performance, but his performance is also just a rather simple short performance that no actor could have done more with than Richardson does. I want to stress that this technically a good performance, but simply this character could not have had more to it than it does.
