Sounds like a lot, right? Well, not compared to the film that holds the 15th position on this list. With a $111 million budget and $1.1 billion to show for it, 'The Lord of the Rings: Return of the King' comes in with an impressive 1,008 percent return on investment. From there we've got 'Mrs. Doubtfire,' 'There's Something About Mary,' and 'The Hangover' followed by 'Jaws,' 'Ghost' and 'Home Alone.' Next up is 'The Passion of the Christ,' 'American Beauty' and 'Star Wars.'
Finally, the first to crack the top five is 'Grease,' which boasts a mere $20 million budget with $394 million in returns. That puts its return on investment at 1,975 percent. 'Pretty Woman' crossed the 2,000 percent point with an ROI of 2,013 percent thanks to its $463 worldwide intake on a $23 million budget. Number three on the list is everyone's favorite indie underdog, 'Slumdog Millionaire.' That one was made for just $15 million and not only went on to collect award after award, but $378 million at the box office and a 2,520 percent ROI, too.
It's the number two film, 'E.T.,' that really takes things to another level. 'E.T.' takes 'Slumdog' by an astonishing 500 percent, courtesy of its $25 million budget and $793 million haul. But even with a 3,172 percent ROI, it's still light years away from the most profitable film of all time. That would be 'My Big Fat Greek Wedding,' which boasts a 6,150 percent return on investment thanks to its measly $6 million budget and $369 million in earnings. So this is why Nia Vardalos got the OK to make junk like 'I Hate Valentine's Day.'
