Mark Duplass has been confirmed as one of four daily keynote speakers at SXSW.

Organisers at the festival in Austin, Texas have also announced the scheduled of Conversations, panels and workshops that will take place during SXSW, which runs March 13-21, 2015.

“SXSW Film’s conference sessions, known for their breadth and quality, lead the conversations about our rapidly changing industry,” said head of SXSW film Janet Pierson.

“We are thrilled that Mark Duplass is one of our keynote speakers because he personifies the SXSW ideal by working energetically as an actor, writer, director and producer of electric work, across film, television and web series.

“Also exciting is our expanded Convergence programming, allowing for a diversity not possible anywhere else. Convergence gives registrants more ease in exploring the intersection of Interactive, Film and Music.”

The first round of 2015 SXSW Convergence Programming announced last week includes more than 60 sessions featuring the likes of Brian Grazer, Russell Brand, Rich Eisen and James Frey.

Conversation participants include Elizabeth director Shekhar Kapur, while there are panels covering Pixar films, DIY theatrical distribution, creative game-changers and the impact of technology on war zone reporting.
