London, Jan 3: Hollywood blockbuster 2012, starring John Cusack and Thandie Newton, is the worst ever science fiction film, according to NASA scientists.

The US space agency said that the end-of-the-world flick is the most `scientifically flawed of its genre'.

Bruce Willis''s `Armageddon', in which an asteroid the size of Texas was broken up by oil workers using drills and a nuclear bomb, was also panned.

Arnold Schwarzenegger''s `The 6th Day' was blasted for a plot where the star is cloned complete with his accent in a few hours.

`Volcano', starring Tommy Lee Jones and Don Cheadle, laughably showed Los Angeles consumed by a super-eruption.

And Rachel Weisz''s `Chain Reaction' spiced up its plot about generating energy using nuclear fusion with a far-fetched kidnap.

Donald Yeomans, head of NASA''s Near-Earth Asteroid Rendezvous mission - study of threats hurtling through space, singled out 2012 as an `exceptional and extraordinary case'.

"The agency is getting so many questions from people terrified that the world is going to end in 2012 that we have had to put up a special website to challenge the myths. We have never had to do this before," the Sun quoted him as saying in California.

Meanwhile, NASA praised Ridley Scott''s `Blade Runner' and `Gattaca' ''starring Ethan Hawke and Uma Thurman as the most realistic. (ANI)
