So starting off its not one of those films which explain everything to the viewer. Its more like your math teacher doing a problem on the black board and just "expecting" you to "understand" it. Does it bring back memories....yes yes it does. Well memories aside, towards the end, the entire movie makes complete sense. Each loose end is tied up perfectly, with a very pretty bow. So patience is a virtue (people with very slow internet speeds understand...don't' you).
The events of the movie takes place some where in the future where Earth is slowly turning out to be uninhabitable to humans. Our protagonist Cooper (Matthew McConaughey), is father of two, son Tom and daughter Murph (named after Murphy's law), lives with his family including his father-in-law, Donald. He is an engineer by profession, but the current situation of man kind forces him to be a caretaker and become a farmer. He is a regular parent who goes to PTA meetings, and during such a meeting the teacher tells him that his son's score is low, hence he has to become a farmer. Cooper fights and asks why he cannot be an engineer. The reply almost gave me a heart attack, he says "We don't need engineers"(Being an engineer myself this quote stung pretty bad).
Meanwhile, Murph feels there is a "ghost" in her room, who has been trying to communicate with her. Cooper brushes this off until one dust storm the dust settles down as a binary code on the floor of murphy's bedroom. This leads them to a secret NASA station where he meets Professor Brand, his daughter Amelia (Anne Hathaway) and the very charming TARS. Cooper is told that Brand has a Plan A and a Plan B to save Earth or atleast the human species. Brand asks Cooper to pilot Endurance, a spacecraft, which will take him and others through wormhole to find a planet for the human kind to survive. Previously other astronauts had been sent through the same wormhole and three potential planets have been zeroed in.
Murph doesnt like it that her father is leaving her. And says the the "ghost" has asked him to stay. He leaves anyway and promises her that he'll be back. The mission starts off with 4 people - Cooper, Amelia Brand, Doyle and Romilly. The journey through space and the worm hole is absolutely breathtakingly wonderful visually.
The entire movie is just not about the mission there's actually some very emotional scenes between Murph and her father and your heart aches for them to get back together. Each of the planets that they go to increases their time on earth, like an hour turns out to be 7 years. The time you cannot loose because like Cooper says, whats the use of finding a solution after all the people on earth have died. So Murph's growing up as her father stays the same age. The discoveries they make has a lot of twists and turns and suddenly you start to wonder exactly how will it end? Can they save the human race? Will cooper see his daughter again?
And most importantly who is murph's ghost?
Do not go gentle into that good night,
Old age should burn and rave at close of day;
Rage, rage against the dying of the light.
