The DVD of Gregory Hoblit's supernatural surprise hit Frequency includes a widescreen, anamorphic transfer, Dolby Digital and Surround Audio, and a respectable amount of extras. Commentary tracks by Hoblit, writer/producer Toby Emmerich, and actor Noah Emmerich add insight into the creative processes behind Frequency, while the documentary "The Science and Technology Behind Frequency" explores the scientific basis behind the film's premise of heightened solar activity allowing a man to talk to his long-deceased father. Likewise, the disc's animated gallery of sunspots and solar flares provides a unique perspective on the film. Another audio track isolates Michael Kamen's score and presents his commentary on the music; the theatrical trailer and DVD-ROM features, such as script-to-screen comparisons, and the film's original website round out this substantial, entertaining DVD.
