Don't waste your time (not intended as a pun!). This is one of the most disappointing films I have ever seen, I love Sci-fi and was really looking forward to seeing this following the great reception it received, the people who liked this movie must have been watching a different version to the one that I watched. It is overlong at nearly 3 hours, where not a lot happens, the acting is wooden and hopeless from everyone except the young girl; Matthew McConaughty as the main character is totally miscast and 'MUMBLES' throughout his entire performance (I have perfect hearing, but was having to strain to hear what he was saying), Michael Caine and John Lithgow are wasted talents in this film, and are not given much to do. But what was most annoying was the never ending oozing over- sentimentality about family 'relationships' that would even have Steven Spielburg blushing! If you go to see this expecting a film about man's push to the stars...forget it. Also the 'revelation' how the girl works out the answer is so ridiculous that it actually made me laugh.
