Arrival (Free screening!). This sci-fi film, based on the novella Story of Your Life by Ted Chiang, subverts the common alien-invasion narrative by taking a much more restrained, scientific look at interplanetary communications. This film screening is hosted by the University of Arizona College of Humanities, and features a post-film discussion led by associate professor Richard Poss from the UA Department of Astronomy. If youโ€™ve never seen it before, trust me, thereโ€™s a lot to talk about after the credits roll. 7 to 9 p.m. Tuesday, Oct. 29. 3233 E. Speedway Blvd. Free. Information.
