No. SXSW does not accept any materials pertaining to submissions outside of the official SXSW Film & TV Submission Application. Unfortunately, we receive too many submissions to accept EPKs, stills, or trailers. Additionally, our audience will only be seeing your film, so we judge based on the work itself.
In keeping with our effort to be a green festival, SXSW also requests that you do not send any physical press kits, photo stills, or any other extraneous material.
