Jane, a struggling but perpetually stoned actress, has a busy day ahead. She has several important tasks on her list, including buying more marijuana. Even though she already has a good start on the day's planned drug use, she eats her roommate's pot-laced cupcakes and embarks on a series of misadventures all over Los Angeles.

'Smiley Face' showcases Anna Faris as a comedy goddess with flawless timing and fearless commitment, delivering a charming, endlessly quotable stoner comedy with strong rewatch value. However, the film sharply divides audiences: while some find it hilarious and engaging, others criticize the pointless, plotless writing and question its plausibility regarding marijuana effects. The humor's effectiveness proves highly divisive, with some laughing throughout while others find it completely unfunny, making it best suited for fans of Faris and lighthearted stoner comedies.
