Ben Affleck makes a cameo appearance in "Clerks II" as a fictionalized version of himself. His role is part of a scene where he participates in a promotional event for "The Boondock Saints II." This cameo serves as a humorous nod to his Hollywood status and connection to Kevin Smith, the film's writer and director. Affleck's appearance adds a layer of self-referential humor, aligning with the film's meta-commentary on the film industry and the nature of celebrity.

Whether "Clerks II" is better than "Clerks" often depends on personal preference. "Clerks," released in 1994, is a groundbreaking indie film that introduced audiences to Kevin Smith's unique style and dialogue, focusing on the lives of two convenience store clerks. "Clerks II," released in 2006, builds on the original with a bigger budget, enhanced production values, and explores themes of adulthood and nostalgia while maintaining the humor and character-driven storytelling. Fans of character development and a more polished approach may prefer "Clerks II," while purists may favor the original.

Becky, played by Rosario Dawson, did not appear in "Clerks III" primarily due to the character's fate and the storyline that Kevin Smith chose to pursue. In "Clerks II," her character had a significant role, but in "Clerks III," the narrative focuses on the aftermath of the characters' lives, particularly Randal and Dante. Smith has mentioned that the story evolved, and while he expressed a desire to include her character, the overall direction of the film did not accommodate her presence.

Yes, Kevin Smith's daughter, Harley Quinn Smith, appears in "Clerks II." She plays the character of "Dante's Daughter," a small but memorable role in the film. The movie, released in 2006, is a sequel to Smith's 1994 film "Clerks" and features the continuing story of Dante and Randal, set years after the original. Harley's appearance adds a personal touch, as she is the daughter of the film’s writer and director, Kevin Smith.
