It’s fair to say “Best in Show” (2000) helped breathe new life into the mockumentary, as well as the repertory led by Christopher Guest and Eugene Levy (which lives on to this day – thanks “Schitt’s Creek”). This behind-the-scenes look at dog shows also serves as a bridge that helped introduce audiences to newer ensemble comedians such as Jennifer Coolidge and John Michael Higgins. Theirs and other characters (Catherine O’Hara) are inspired in their quirkiness. Fred Willard is hilarious – he seemingly improvs his entire performance as the dog show TV announcer – but as a result probably gets too much screen time.
