A Clarification...
Hi,
I'm not a film student, so I have nothing to offer in terms of critique, but I am a counseling graduate student and I've seen this movie as an undergraduate and now as a graduate student.
I just wanted to point out that Mabel is suffering from a mental illness (if you support the prevailing view), but it's *not* bipolar disorder. I can understand why you might think that, and that is indeed what I believed when I saw the movie for the first time.
"Under the Influence" can be taken quite literally--Mabel is an alcoholic. It's portrayed in a very subtle way, so it's hard to pick up right away, but there are indicators.
At the beginning of the film, Mabel goes to a bar and downs a drink rather quickly. Anybody else who would down a drink like that would be more than a little tipsy, but Mabel isn't. In fact, she is well known at the bar and doesn't seem to be too fazed. It's well into the evening before she stumbles into her house drunk with the guy who's to be her one night stand, suggesting she's built up quite a tolerance to alcohol.
Another telling sign concerns what she remembers the next morning. Mabel doesn't remember anything from the night before and continues to believe the man she slept with is Nick. This is a classic indicator of a blackout. The fact that her memory lapse lasts so long is an indicator that this isn't your normal hangover...
Mabel (and the camera) keeps going to the door marked "PRIVATE." The audience is led to believe this is where she keeps her alcohol (a common behavior for women with a drinking problem because there's more of a stigma for female alcoholics.)
Just before she is hospitalized, she admits to drinking and taking pills. If I remember correctly, she abuses Valium (a pretty dangerous mix with alcohol). The weird tics and the strange behavior are all alcohol induced. Just like any other drug, alcohol, if taken frequently and chronically enough, can induce anxiety like symptoms.
Just my two cents. The movie description just says Mabel has a "mental illness," but like I said, I think that's to add to the mystery. She certainly is dependent on Nick for approval and one could say "under the indluence" has a double meaning.
