ELLIE PARKER *

(one star)

NAOMI Watts is the only explanation for the existence of the student-y digital video feature “Ellie Parker,” in which she plays a struggling L.A. actress going on auditions, fighting with her boyfriend and vomiting blue ice cream.

And yes, she cries yet again, extending a nearly unbroken record of blubbering every time she gets near a camera. Watts gives her all, though this made-on-the-fly movie written and directed by a friend of hers from the “Mulholland Drive” set doesn’t merit it.

The script about the title character’s acting classes, psychotherapy (the two are nearly indistinguishable), car trouble and other workaday concerns seems vaguely authentic and has a teaspoonful of satire. Ellie says, “I’ll let you in on something: ‘Therapist’? The rapist.” But a documentary on Watts’ life would have been far more watchable.

Former celebrity Chevy Chase shows up to do some shtick in a cameo as Ellie’s agent.

Running time: 94 minutes. Not rated (drug use, sex, profanity, brief nudity). At the Angelika and the New Metro Twin.
