Bringing in nearly $700 million worldwide, Interstellar didn’t rack up as much as Christopher Nolan’s last original sci-fi venture, but one imagines Paramount is pleased with the gross. An experience like no other film in IMAX last year, they’re now offering one final screening in the format at select AMC Theaters this Saturday, February 21st, 2015. Featuring 12 minutes of new behind-the-scenes footage, you can find the list of theaters here, and ahead of the event we have a new conversation tied to the film.

A few weeks ago at Santa Monica’s Aero Theater, Nolan stopped by for a Q&A with another leading director in the field of science-fiction: Rian Johnson. With around 30 minutes of their conversation captured, they discuss how Nolan and crew made profit from their corn, the rear and front projection used on set, working with Hans Zimmer on the score (and never using temp music), and much more. Check out the full conversation below and listen to our in-depth discussion of Interstellar here.
