When it comes to Brett Kelly’s filmography, one name that consistently stands out is Bad Santa (2003)—and for good reason. Brett Kelly delivered a memorable performance in this dark comedy, which has since become his highest-rated movie among both critics and audiences. The film’s sharp humor and unexpected heart clearly resonated with viewers, solidifying Brett Kelly’s role as a standout young actor at the time. On the other hand, when we look at Brett Kelly’s later work, particularly Bad Santa 2 (2016), the reception wasn’t quite as strong. While Brett Kelly did reprise his role, the sequel received notably lower ratings across the board. So, while Brett Kelly remains closely associated with the Bad Santa franchise, the contrast between the original and its follow-up is pretty clear. In summary, Brett Kelly’s career high in terms of ratings comes from Bad Santa (2003), whereas Bad Santa 2 (2016) marks his lowest-rated project to date.
