Dan Aykroyd received his only Oscar nomination so far for portraying Boolie Werthan in Driving Miss Daisy.
I must say though despite the limitations of his part Aykroyd does give a pretty descent performance. He makes Boolie a rather likable character, and does have a certain charm in his part. Aykroyd makes Boolie a man who really wants what is best for his mother, and he fully does understand here. He also though does mind taking some gentle humor around her due to her stubbornness.
I certainly like what Aykroyd does with his part never overacting his reactions but keeping them rather simple but appropriately humorous. Also Aykroyd when possible shows that Boolie honestly cares for his mother through just a subtle warmness and ease he has in his scenes with Tandy. He never overplays it, but makes it wholly apparent.
After that Aykroyd just is not given a whole lot to do besides age, which I must say he does well, and really does not leave it only to the makeup. He carefully changes his mannerisms throughout to make a very natural progression as he ages. Otherwise than that Aykroyd gives a nice supporting performance, that really does support the two leads well. He is given few scenes to shine, but Aykroyd always stay good throughout the entire film.
