Inside Television's Greatest: I Love Lucy-William Asher Interview

Producer/director William Asher, who is probably better known as the producer/director behind Bewitched,  ended up directing 110 of the series' 179 episodes by the time the show ended in 1957. He shares what it was really like being on that set, his initial tensions with Lucy, and directing William Frawley and Vivian Vance who did not like each other.  He also discusses directing Lucy and Desi in the later episodes when tensions were quite high.  But he also talks about how in awe he was of the magic of these four stars together and especially of the talent of Lucille Ball.
