Look out, illegal aliens (and we don't mean the human kind)! Tommy Lee Jones and Will Smith are the nattily dressed government agents whose top-secret job it is to track down any extraterrestrials landing on Earth and keep tabs on the ones living incognito as humans, all the while keeping the truth hidden from the general public, in this slyly funny, effects-filled sci-fi comedy. With Linda Fiorentino, Vincent D'Onofrio. 98 min. Standard; Soundtracks: English Dolby Digital 5.1, Dolby Digital Surround, French Dolby Digital Surround; Subtitles: English, Cantonese, French, Mandarin, Spanish; audio commentary.
