Overlooked Films That Became Unexpected Hits

I’m always fascinated by films that start with little fanfare and somehow find a massive audience. One that comes to mind is “The Blair Witch Project.” It was made on a shoestring budget with unknown actors, and its marketing leaned into that mysterious, grassroots vibe. For a while, it felt like this quiet little rumor, and then it seemed like everyone was talking about it. It really showed how word-of-mouth and a clever concept could turn a small signal into a worldwide phenomenon. What other films have you seen follow a similar path from obscurity to becoming a cultural moment?
