The film is told in flashback by an older version of Pi to a writer, who has heard he has an amazing story to tell - and so he tells him this wondrous story of he survived, as a young man, in a lifeboat with a tiger called Richard Parker, after the ship he was on sunk.
However, the best scenes happen out at sea, when the ship sinks in a whirlwind of rain and when Pi is stranded in the ocean. Light is used to a great effect in a scene where Pi looks beneath the waves and sees a flurry of strange and lovely images - including a colourful glimpse of galaxies and stars.
Whilst those scenes are brilliant for their dreamlike quality, the tiger is incredible for its realism. I believe it must be mostly CGI, but it looks very real. It also sounds very real - its growling sounds threatening and close.
I must say that the three actors who portrayed Pi were all excellent as well. They were all completely believable, and even though they were dealing with quite a dramatic story, they came across as melodramatic.
Pi is a charming character, one which I enjoyed watching and who I sympathised with - which is fortunate, because as an audience we spend a lot time with him.
I won't spoil the ending for anyone here, but if you have an interest in faith, human nature or philosophy, and a friend to discuss it with, you'll be talking for hours. It is a very thought provoking film, if you wish it to be, and I am sure people will have lots of different interpretations.
This is why I think The Life of Pi may become a classic film one day - because its so lovely to watch, and yet so thought provoking.
Who knows, ether way I can highly recommend it, and I think I may go see it again, but in 3D.
