Hamm will play Dr. Granier, a NASA official who recruits Helen (Connelly) for the scientific team investigating an alien’s arrival on Earth. Reeves plays Klaatu, the alien who has a simple message: Live in peace or be destroyed. Scott Derrickson (The Exorcism of Emily Rose) will direct the update of Robert Wise’s 1951 classic from a screenplay by David Scarpa. Principal photography began Dec. 12 in Vancouver. Hamm started shooting Tuesday, according to the studio.
