Will Smith, the late James Avery (Uncle Phil), and Karyn Parsons (Hilary) are the only cast members who appear in all 148 episodes of “The Fresh Prince of Bel-Air,” meaning that co-lead Alfonso Ribeiro (Carlton) isn’t actually in every episode, among other family members. Parsons is technically absent from the Season 5 episode, “Love in an Elevator,” as the bulk of the episode finds Will, Carlton, and Jazz (DJ Jazzy Jeff) trapped in an elevator on the way to Will’s bachelor party. While stuck, the three friends reminisce about their experiences together over the years, and Parsons appears in the trio’s flashbacks. The episode was one of several “clip shows” deployed over the course of the series’ run.
One could argue that DJ Jazzy Jeff appears in every single episode because he is seen playing basketball during the opening credits — a nod to his and Smith’s real-life music success as DJ Jazzy Jeff and The Fresh Prince. But the rapper and former Smith collaborator is only credited for a total of 46 episodes as the fan-favorite supporting character Jazz.
“The Fresh Prince of Bel-Air” is currently streaming in its entirety on HBO Max, along with the recent reunion show from November, 2020.
