Aykroyd is, of course, most well known for his comedic acting, and it's in comedy where he has truly left his mark. However, he has had dramatic roles, as well. In 2001's "Pearl Harbor," Aykroyd played Captain Thurman, a Naval intelligence officer spearheading the monitoring of Japanese espionage attempts. As pointed out by the Chicago Tribune, the character is said to be a composite of multiple real-life people.
In 1989's "Driving Miss Daisy," he played Boolie Werthan, the son of the titular character. The role truly offered Aykroyd a chance to stretch his range, playing the character between the ages of 40 and 65. He's the one who buys Daisy her 1949 Hudson Commodore, and hires Hoke Colburn, played by Morgan Freeman, to be her chauffeur, thus laying the foundation for the film's exploration of racism in America and particularly in the South.
While drama may not be Aykroyd's go-to form of creative expression, these roles gave him an opportunity to showcase his talent as an actor.
