Filmmakers Karan Johar and Shekhar Kapur can't stop praising Oscar-winning filmmaker Ang Lee's "Life Of Pi", based on Yann Martel's Booker Prize winning novel of the same name.

The movie opened here Friday in four languages - English, Hindi, Tamil and Telugu and collected Rs.3.5 crore.

" 'Life Of Pi' - must watch!! Its message will have multiple interpretations and will be open to post viewing analysis. That's the fun of it," Karan tweeted Sunday.

It has been released in 2D and 3D format and Kapur liked the movie so much so that he went to watch it a second time.

"Watching 'Life Of Pi' second time in two days. Brought my daughter and her friends. Nice to see a full house and lots of kids. Fantastic movie," Kapur tweeted.

"Life Of Pi" narrates the tale of a boy who is adrift at sea in a lifeboat with a Royal Bengal tiger after his family is drowned in a shipwreck.

It features Indian actors Tabu and Irrfan Khan and newcomer Suraj Sharma.

The movie was shot in the hillside town of Munnar along with the elegance of Pondicherry - all on 3D.
