A nice surprise: director Stefan Schweitert says he can make his way to the festival after all to answer questions after the fabulous “Echoes of Home.” We thought we’d have to test our technical abilities by setting up an Ichat with Berlin, so this will make it much easier, and homier. Get one, lose one category: Michael Cleverly, the author of a book on Hunter S. Thompson, will not appear on Friday with “Gonzo,” as promised in the program. However, new Oscar winner Alex Gibney will appear with “Gonzo” on Saturday as well as “Taxi to the Dark Side” on Sunday.
