Zemeckis is clearly going for broke here, with his liberal borrowings from the "trip" sequence in Stanley Kubrick's 2001 and from the patriarchal sentimentality of Spielberg's Close Encounters of the Third Kind and E.T., not to mention his over-the-top use of McConaughey.
As directed by Robert Zemeckis (who won an Oscar for "Forrest Gump" and gave us the "Back to the Future" films, among others), "Contact" seems to be striving for a blend of the excitement of "Close Encounters of the Third Kind" and the intelligent musings of "2001: A Space Odyssey."
It has a measure of the awe and spectacle of 2001: A Space Odyssey, and an element of the mystery and hope offered by Close Encounters of the Third Kind.
For me, only a few other films can approach pure science fiction, among them "Things to Come," "The Day the Earth Stood Still," "Fahrenheit 451," "Close Encounters of the Third Kind," "A.I: Artificial Intelligence," and, of course, the greatest of them all, "2001: A Space Odyssey."
It'll be compared most closely with Close Encounters of the Third Kind, but that's only because it treats grand-scale scientific inquiry with some respect.
Just think of Roswell, N.M., or the glowing eggheads in Close Encounters of the Third Kind.
