Dane Dehaan plays Major Valarian, an officer whose task is to retrieve a valuable object. Dehaan, at age 31, looks a good ten years younger on screen, but he is easy to look at, and a believable action hero.
The movie was directed by Luc Besson, who gave us another memorable Sci-Fi movie in "The Fifth Element" (1997) with Bruce Willis starring.
I won't give away any of the plot, except to say that this movie is Sci-Fi on a grand scale, and it works - in spades!
The film is filled with some interesting characters, and some equally interesting aliens.
I recommend it without rservation.
