Today Michael Moore, American documentary filmmaker and author, showed up for a scheduled 7-minute segment on MSNBC’s “Morning Joe.” The conversation got so intense and powerful that the host, Joe Scarborough, waved off commercial breaks, allowing Moore a television luxury — the chance to express his thoughts in complete paragraphs instead of in sound bytes. The conversation lasted for 45 uninterrupted minutes. The “Morning Joe” has never done this before.  The producer said this “was the longest segment ever in the history of this show.”
