Suspension of disbelief is a challenge when the movie glosses over so many of its logistical details (like, where does one buy an old NASA space capsule?), and in trying for a kind of Capra-esque, eccentrically Western spin on the American dream, the Polish twins--director Michael and cowriter/actor Mark (making their mainstream debut after such indie hits as Twin Falls, Idaho and Northfork)--are only marginally successful in making Charlie's ambition genuinely believable. The film works much better as a kind of post space-age fable for families, and it's just involving enough to make its climax emotionally rewarding, mostly because Thornton, Madsen, and their costars (including Bruce Dern and Tim Blake Nelson) handle the delicate material with the earnestness it needs to be marginally convincing. Elton John's "Rocket Man" is predictably heard over the closing credits (accordingly, Charlie's launch-time is "zero hours, nine a.m."), and at a time when several adventurous entrepreneurs (including Amazon.com founder Jeff Bezos) are gradually developing a civilian space-flight industry, The Astronaut Farmer is an admirable yet forgivably flawed reminder that we should never stop reaching for the stars. --Jeff Shannon
