Though theoretically this movie would be based in the distant future, Christopher Nolan has done a splendid job in focusing on the story over futuristic technology and gadgets. Interesting to note that Nolan appointed a professional consultant for use of many astronomical concepts such as time and space relativity, wormholes, black holes, etc. so that the movie does feel believable. Fantastic performances by a superb cast, awesome background score by Hans Zimmer and mind-blowing visual effects make Interstellar one of the greatest sci-fi movies of all time.
