Comedy Central’s “Reno 911!” has been one of my favorite channel-surfing stops, so it was a relief to discover that the joke holds up for nearly 80 minutes on the big screen. This “Cops” spoof moves the group to Florida for a police convention, but its emphasis on caught-on-tape idiocy remains. The sexual humiliation of its characters continues too, especially in an extended long shot that allows us to see the various goings-on in everyone’s hotel room at once. It’s the crassest thing I’ve witnessed in a long time, yet it also reminded me of the deadpan, intricately staged set pieces of French filmmaker Jacques Tati (Playtime).
