LOS ANGELES - There's a fresh candidate in the running for worst movie of 2007 honors. "I Know Who Killed Me," a ridiculous thriller (minus the thrills) starring the embattled Lindsay Lohan in a dual role, has all the hallmarks necessary for qualification: A nonsensical plot that grows sillier by the second, tawdry special effects, heavy-handed symbolism that's big on electric-blue hues and mechanical performances are all culprits as far as the title's concerned.

We'll probably never know whether Lohan's most recent difficulties took their toll on the picture's box office potential, because either way, this movie doesn't even warrant one star. It was released on Friday without screening in advance for critics.

Lohan plays Aubrey Fleming, an aspiring writer and promising pianist who disappears one evening while out with friends only to turn up in a hospital minus a hand and a leg after barely escaping from a madman's torture chamber.

When her distraught parents (Julia Ormond, Neal McDonough) rush to her side while guys in FBI T-shirts methodically hunt for her would-be killer, she doesn't recognize the name they call her, insisting that she's Dakota Moss, a pole dancer in a seedy strip joint who subsequently has reason to believe she may actually be Aubrey's identical twin sister.

Don't even ask.

You might, however, find yourself asking just what was Lohan -- whose promising career already has taken a few hits with such films as "Just My Luck" and "Georgia Rule" -- thinking when she signed on to this nonsense?
