Tim Meadows is one of the most underrated “Saturday Night Live” cast members and it’s unfortunate he never became a more prominent comedic film star. His highlight is “The Ladies Man” (2000) and it, too, is underrated. Granted, ribald sex comedies are a niche taste, but you don’t feel icky cheering for Meadows, who generates genuinely oblivious sincerity as a talk show host who likes to fool around. The plot’s middle-of-the-road compass reins in the raunch to appropriate levels. Plus, there’s a Julianne Moore cameo and vengeful husband Will Ferrell provides an out-of-nowhere musical number inspired by “West Side Story.”
