10 Films You Didn't Realise Were Gigantic Successes

10. Once (2007)

Musicals - or films about/involving a lot of music - have a habit of chipping away at the box office and sticking around for a while.

So, when a romantic musical drama set in Ireland wandered onto the scene in 2007 - after years stuck in development - many rightfully thought that the mellifluous film (with a 97% Rotten Tomatoes score) would make a bit of noise and convince people to head to the cinema to see what all the fuss was about.

At both the Sundance and Dublin Film Festivals, Once won the audience awards and even Steven Spielberg praised the little flick for giving him 'enough inspiration to last the year.'

The film didn't break the wheel or earn anywhere near as much as other musical entries like The Greatest Showman (2017) or A Star is Born (2018), but it still performed admirably based on how much the plucky indie cost to produce.

On a $150,000 budget, the film went on to gross $23.3 million worldwide. Which is quite staggering when you really think about it.

An Academy Award for Best Original Song (for the film's standout tune, 'Falling Slowly') was the icing on the cake for a picture which - though critically lauded - isn't remembered or respected anywhere near enough for its fantastic performance and success in theatres all around the world.
