Grant-era sci-fi comedy about legless bad guy Kenneth Branaugh bargaining away U.S. territories with world governments Ñ intending to encapsulate the 1965-70 CBS TV series berplot. Salma Hayek shows some. Closing Fresh Prince title tune samples Stevie WonderÕs ÒI WishÓ (1976). Elmer Bernstein dances around his original main theme for an hour.
