Well, Bernard Pivot is still a literary institution in France, his "Apostrophes" remaining THE reference in matter of literary emission and being regretted by people nostalgic of a time where literature had a place on French TV. According to the extracts from different "Apostrophes" episodes I saw on youtube, Pivot was usually respectful with his guests. It's a pity that he acted so badly with Hank for a question of audience ratings. He didn' t loose control one second, it was just a "mise en scéne" (you know, like a show where everything is anticipated in advance), he did want Buk to react like a drunkard, I've even read that some bottles had been provided to him by the staff...
As for François Cavanna, the guy who told Hank to shut the fuck up and threatened him with his fist, he apologized himself one or two days later within his own newspaper ( "Charlie Hebdo").
Pessimist, if you need some help, I'm here ;)
