The "river " movie-as opposed to road movie- was born with Huston (African queen,1950),then continued by Preminger's"River of no return"(1954)."The far horizons" is an entertaining adventure yarn,with a nice cinematography ,a good use of the cinemascope and a very fine cast.Donna Reed stands out,her portrayal of the Indian heroine is very modern,and the last sequence is totally unusual in this kind of movie.
The story is divided into a prologue ("civilization"),the main part (the expedition),and an epilogue (back to" civilization").The dialogue is wittier than in an average western.Some remarks about women's position in both societies are smart .
The "river movie" will reach its artistic peak during the seventies with Herzog's "Aguirre,der Zorn Gottes"(1972)(also an expedition!),the same year as John Boorman's "deliverance".In the nineties,it was still hip,as "the river wild" (1994)shows.
