While going through footage for the DVD extras, we came across some clips that didn’t make it in the documentary. We think they're still really interesting, and want to share them with you all!

What are your thoughts on time travel paradoxes? In this clip, Wanda Gregory, Lecturer in Interactive Media Design at the University of Washington and Brooks Peck, Curator at the Museum of Pop Culture in Seattle, talk about time travel paradoxes in movies like Back to the Future, Groundhogs Day, and The Butterfly Effect.

"What's unclear is whether there's a way to jump into some sort of wormhole or time tunnel and either go back into the past or the future."

We found some raw footage from our interview with Seth Shostak, Senior Astronomer at the SETI Institute. Here he discusses his thoughts on why people are interested in time travel, and what are the possibilities in store.
