Nobody likes to talk about Kevin Smith more than Kevin Smith, which makes the documentary “Clerk” a bit strange. The filmmaker, podcaster, and comedian has spent over 25 years sharing intimate details about himself on all forms of media, inviting outsiders into his private life, exploring all kinds of topics related to the business of being Kevin Smith. Close friend and documentarian Malcolm Ingram (“Small Town Gay Bar”) clearly thinks there’s more to mine when tracking the life and times of Smith, offering “Clerk,” which is more of a general overview of personal and professional difficulties endured by Smith, who’s front and center for the picture. Those new to Smith’s universe are certainly going to get more out of the movie, which offers a decent education on the helmer’s history and choices. Longtime fans are going to hear some of the same stories here, but Smith’s arc of triumph remains compelling, even in an abbreviated form. Laughs are plentiful and memories are crystal clear, following Smith as he returns to past experiences for Ingram, trying to make sense of a career that’s endured for decades.
