Smiley Face is something of an endurance test. How long can the film keep going before falling apart due to its own flimsiness. Thanks to star Anna Faris, it pretty much does make it to the finish. The third act–thanks to the bookending device (the film is told in flashback, narrated by Roscoe Lee Browne, who Faris is imagining talking to her)–lacks momentum but there’s only so much the movie could do. It is just about Faris getting too stoned and messing up her day. There’s nothing more to it.

After Browne introducing Faris, the film flashbacks to her morning. She’s got a busy day–an audition (she’s an actress) and she’s got to pay the power bill in person. So she gets a stoned before starting out, only to get more stoned after she eats her roommate’s cupcakes. Turns out they’re pot cupcakes. Now, Smiley Face does a fine job with the attention span and the erratic hold on reality of a stoned protagonist, but there are some leaps–would Faris actually remain conscious after eating so much pot, would she still be stoned ten hours later as the story wraps up. She narrates most of the first act and implies her tolerance isn’t extreme… but whatever.

During the first act she also introduces the roommate, Danny Masterson; they hate each other and he psychologically terrorizes her. He’s one of the film’s many leaps in logic. He’s there to be a punchline (in Masterson’s case, a repeated, non-emoting one). The most exceptional thing about Faris’s performance is she manages to navigate the film’s anti-character development and succeed anyway.

We also meet her dealer, Adam Brody. Who’s a white guy with dreads. Fake dreads, but it’s not clear if the dreads are supposed to be fake (they’re obviously fake). He’s done giving Faris a free ride on her pot, so she’s got to bring him money at a hemp festival–pre-marijuana legalization pot culture is going to be hard to explain someday soon–see, since she ate all the cupcakes, she needs to make more. And then she’s got to pay the power bill and get to her audition.

Smiley Face uses, occasionally, superimposed text cards enumerating Faris’s tasks for the day. It forecasts the story. Maybe the funniest and smartest thing about the script, as the protagonist is debilitatingly stoned, her to do list ain’t getting done.

Besides a mishap getting on the bus–Faris is too stoned to drive (the film, at least until the second act, is often just showcases for her physical comedy skills)–she basically follows the plan. Though she does burn up all the weed and doesn’t have money to buy any more. The audition, with Jim Rash as the receptionist and Jane Lynch as the casting agent (the film’s rife with cameos, mostly in the first half), is pretty funny. Definitely could’ve gone longer but the film’s already started backing up a bit from being through Faris’s perspective, narrative distance-wise, to being about Faris’s experiences.

Eventually John Krasinski comes into the story–he’s a friend of Masterson’s who has a crush on Faris, which is summarized in a hilarious montage–because she needs a ride and someone who can lend her money to pay Brody. They just need to go to Krasinski’s dentist appointment first.

Things don’t go as planned–actually not a single thing in Smiley Face goes as planned; it’s not really a comedy of errors because things going well doesn’t seem remotely possible. It’s just how is Faris going to screw it up. Though she’s decidedly passive in most of her problems in the second half. For example, when she goes to hide at an old professor’s house and his mom–Marion Ross in a fun cameo–mistakes her for the new teacher’s assistant… well, it’s not like Faris can tell her the truth, not given the situation.

The scene with Ross changes the narrative trajectory all the way to the finish, even though there’s some attempt at acknowledging Faris’s original plans. There are talking dogs, there’s John Cho and Danny Trejo as sausage delivery drivers, there’s a workers of the world unite speech, there’s a ferris wheel. There’s even a Carrot Top cameo.

Dylan Haggerty’s script gets real lazy in the third act. The movie needs to be over and the whole journey aspect has gotten slowed way down thanks to all the narrative tangents. So there’s a perfunctory deus ex machina, which comes early enough the narrative could recover. It just doesn’t. Time for the movie to be over.

The film’s competently executed. Shawn Kim’s photography is fine. Director Araki does a little better with the editing than the direction, but Smiley Face doesn’t need a lot of direction. It just needs Faris to be funny; she obliges.

Supporting cast-wise… Krasinski is best, but only because he gets the most screen time. No one’s bad. Not even Masterson. The film figures out how to utilize his driftwood presence. Cho’s actually a little bit of a disappointment, but it’s the part more than the performance.

Smiley Face is eighty-five sometimes long minutes, but there’s always something ranging from funny to hilarious just on the horizon. Until the finale, unfortunately.
