The protagonist is Piscine Molitor "Pi" Patel, an Indian boy from Pondicherry, India, who explores issues of spirituality and metaphysics from an early age.
While later recounting his life there, he offers insight on the antagonism of zoos and expresses his thoughts on why animals react less negatively than proponents of the idea suggest.
It opens with a goat being fed to another tiger, followed by a family tour of the zoo, during which his father explains the aggressive biological features of each animal.
At the age of fourteen, he investigates Christianity and Islam, and decides to become an adherent of all three religions, much to his parents' dismay (and his religious mentors' frustration), saying he "just wants to love God".
A few years later in February 1976, during the period when Indian Prime Minister Indira Gandhi declares "The Emergency", Pi's father decides to sell the zoo and emigrate with his wife and sons to Canada.
The second part of the novel begins in July 1977 with Pi's family aboard the Tsimtsum, a Japanese freighter that is transporting animals from their zoo to North America.
Pi manages to escape in a small lifeboat, only to learn that the boat also holds a spotted hyena, an injured Grant's zebra, and an orangutan named Orange Juice.
A tiger has been hiding under the boat's tarpaulin: it is Richard Parker, who had boarded the lifeboat with ambivalent assistance from Pi himself sometime before the hyena attack.
Frightened, Pi constructs a small raft out of rescue flotation devices, tethers it to the bow of the boat, and makes it his place of retirement.
He begins conditioning Richard Parker to take a submissive role by using food as a positive reinforcer, and seasickness as a punishment mechanism, while using a whistle for signals.
Soon, Pi asserts himself as the alpha animal and is eventually able to share the boat with his feline companion, admitting in the end that Richard Parker is the one who helped him survive his ordeal.
Soon, Pi and Richard Parker regain strength, but the boy's discovery of the carnivorous nature of the island's plant life forces him to return to the ocean.
Two hundred and twenty-seven days after the ship's sinking, the lifeboat washes onto a beach in Mexico, after which Richard Parker disappears into the nearby jungle without looking back, leaving Pi heartbroken at the abrupt departure without even a farewell.
Pi then offers them a second story in which he is adrift on a lifeboat not with zoo animals, but with a Taiwanese sailor with a broken leg, the ship's cook, and his own mother.
[13] The name Richard Parker for the tiger was inspired by a character in Edgar Allan Poe's nautical adventure novel The Narrative of Arthur Gordon Pym of Nantucket (1838).
Richard Parker is a mutineer who is stranded and eventually cannibalized on the hull of an overturned ship, and there is a dog aboard who is named Tiger.
Martel also had another occurrence in mind in the famous legal case R v Dudley and Stephens (1884), where a shipwreck again results in the cannibalism of a cabin boy named Richard Parker, this time in a lifeboat.
[16][17] Martel has mentioned that a book review of Brazilian author Moacyr Scliar's 1981 novella Max and the Cats accounts in part for his novel's premise.
He recounts the story of his life and his 227-day journey on a lifeboat when the ship he sailed sinks in the middle of the Pacific Ocean during a voyage to North America.
[32][33] ReviewofBooks said on the critics consensus, "Yann Martel is a master story teller and he weaves a tale that is entertaining and thought-provoking and at the end, he challenges you to believe it all.
[35] Brian Bethune of Maclean's describes Life of Pi as a "head-scratching combination of dense religious allegory, zoological lore and enthralling adventure tale, written with warmth and grace".
[36] Master Plots suggested that the "central themes of Life of Pi concern religion and human faith in God".
"[41] In 2010, U.S. President Barack Obama wrote a letter directly to Martel, describing Life of Pi as "an elegant proof of God, and the power of storytelling.
The premier/original cast contained only six actors – Tony Hasnath (Pi), Taresh Solanki (Richard Parker), Melody Brown (Mother), Conor Alexander (Father), Sanjay Shalat (Brother) and Mark Pearce (Uncle).
