20 HUGE Hit Movies NOBODY Saw Coming

When we're all long gone, box office analysts will still be trying to make sense of My Big Fat Greek Wedding's box office run - the true anomaly to own all other anomalies.

Despite being a $5 million rom-com with few major names among its cast and a virtually unknown leading lady in Nia Vardalos, the film performed well enough during its initial limited bow to get a wide theatrical rollout.

And yet despite never hitting the #1 spot at the box office, it legged out to an utterly insane $368.7 million worldwide - seemingly a result of electric word-of-mouth and the relatability of its broad concept, albeit told from a refreshingly unique perspective.

Furthermore, this made it the highest-grossing rom-com in Hollywood history - a distinction it still holds almost 25 years later, and one not even its two sequels could surpass.

Truly, we will probably never see another rom-com enjoy this level of surging momentum ever again.
