"Life of Pi" is coming to the big screen, and the trailer is finally here.

The upcoming movie, based on Yann Martel's bestselling novel "Life of Pi," is currently in post-production and is directed by Ang Lee. Footage from the film adaption was presented at CinemaCon in the spring, according to the Huffington Post.

Published by Mariner Books in May 1, 2003, the book is about a young man's jouney as he finds himself adrift in the Pacific Ocean. The book's website describes:

"The son of a zookeeper, Pi Patel has an encyclopedic knowledge of animal behavior and a fervent love of stories. When Pi is sixteen, his family emigrates from India to North America aboard a Japanese cargo ship, along with their zoo animals bound for new homes."

"The ship sinks. Pi finds himself alone in a lifeboat, his only companions a hyena, an orangutan, a wounded zebra, and Richard Parker, a 450-pound Bengal tiger. Soon the tiger has dispatched all but Pi, whose fear, knowledge, and cunning allow him to coexist with Richard Parker for 227 days while lost at sea. When they finally reach the coast of Mexico, Richard Parker flees to the jungle, never to be seen again. The Japanese authorities who interrogate Pi refuse to believe his story and press him to tell them "the truth." After hours of coercion, Pi tells a second story, a story much less fantastical, much more conventional--but is it more true?"

The book has gotten rave reviews.

The New York Times Book Review - "Life of Pi could renew your faith in the ability of novelists to invest even the most outrageous scenario with plausible life."

Los Angeles Times Book Review - "A story to make you believe in the soul-sustaining power of fiction."

The New Yorker - "This breezily aphoristic, unapologetically twee saga of man and cat is a convincing hands-on, how-to guide for dealing with what Pi calls, with typically understated brio, 'major lifeboat pests.'"

The trailer features footage of a teenage boy and a 250-pound Bengal tiger stranded on a tiny lifeboat and adrift at sea.

A movie tie-in version of the novel will be released on Oct. 2, 1012.

Starring Suraj Sharma as Pi and supporting cast members Tobey Maguire and Irrfan Khan, "Life of Pi" movie is set to release in theaters Nov. 21, 2012 in 3D.
