I think we should make an effort to see the commentary/deleted scenes in Ice Storm and try to determine what his comments might imply about the cigars in BBM.
On the other hand, I've realized a couple of things since I last contributed to this thread.
1) Ang is not the world's most articulate person when he's speaking, at least in English, at least in interviews. Sometimes his descriptions of the plot of BBM seem almost ... oversimplified. So it's possible that a commentary would be disappointing because his actual work as a director is much more nuanced than he would describe it, speaking.
2) Having since read the screenplay of the deleted hippie scene, I'm not sure I'd even want to see it!
