Here are the last minute updates to this year's SIGGRAPH, among them the presentation of Ben Snow about the work on Episode 2.
Ben Snow, Visual Effects Supervisor, will appear at AWGUA, the Alias/Wavefront User Group meeting, and he will talk about the work for Star Wars Episode 2. Also present will be Ken Hahn, from Imageworks talking about Spider-Man. Seems also that Jenn Emberly has dropped from the Chuck Jones Special Session. Conversely I have it on good authority that Rob Coleman will be the closing speaker of the Episode 2 Special Session. More info here:
One final update will be given summarizing all the relevant ILM and VFX events.
