If you don’t know the name, you’ve been remiss in keeping up with your BBC America viewing. Steve Coogan’s greatest TV creation, a dumb, shallow and embittered talk show host with a jones for ABBA — and himself — has been the subject of a few series on the Beeb — the best of which have all concerned the downward spiral of his career — local radio, voice overs for industrial films (and worse), hosting small time, small town events of various types. Never shy about forcing people to remember he USED to be somebody. This was a hit in the UK, probably won’t blow up in the US. Limited release, the first week of March. But if you know the character and the show, “Ahaaaaa.”
