One of the all-time masters of sci-fi and blockbuster filmmaking at large returns this week, as Steven Spielberg's Disclosure Dayopens under a fair amount of mystery for a project this large, with Emily Blunt, Josh O'Connor and Colman Domingo starring in a nostalgia-heavy adventure picture about a mysterious organization's cover-up of human contact with extra-terrestrials. Jurassic Park screenwriter David Koepp penned the script from an original story by Spielberg himself. Early critical response has been generally positive, though it remains to be seen if the picturecan recapture anything like the box-office magic of Spielberg in his heyday.
