The Los Angeles Times is in Austin for South by Southwest, the the annual festival of film, music, technology, art, culture, tacos, barbecue, partying - and something of a laboratory think tank for the future.

Times film writer Mark Olsen (@IndieFocus) talks with @marcmaron, who's expanding his wings as a movie actor, along with director @lynnsheltonfilm, who saw him as a star. Olsen also interviews @alexgibneyfilm, whose documentary about Theranos founder Elizabeth Holmes, THE INVENTOR: OUT FOR BLOOD IN SILICON VALLEY, is set to debut on HBO.

And in a preview of next week's episode, Austin native Ethan Hawke shares his affection for SXSW, and says "its DNA is a little more punk rock than any other festival in America."
