Filming schedules became an issue for Helms, as he continued to get starring movie roles. Due to his rising popularity following The Hangover, Helms split time between The Office and movie projects. That resulted in multiple periods of absence from Andy Bernard throughout The Office.

Dakota Johnson had a small but significant role in The Office finale, playing an accountant who replaced Kevin Malone. Despite her limited screen time, Johnson's cameo could have changed the course of her career if her character had been further developed.

"The Office" had a star-studded cast of leading characters, but other celebrities appeared, too. Idris Elba, Kathy Bates, and Will Ferrell had recurring roles on the comedy series. Other stars, like Jack Black, Jim Carrey, and Joan Cusack, had brief cameos.
