Director Erik Matti, who has dubbed the project the most challenging in his storied career with over two years of production, shared the good news on his Instagram page Wednesday.

Posting a screenshot of the score, Matti wrote: "As if today is not important enough. We open in over 170 cinemas nationwide. And... Rotten Tomatoes score just hit 100%! Iho de puga guid!"

As of writing, the "Tomatometer" of "BuyBust" is based on five published reviews from accredited critics of the website, including those from Hollywood Reporter, Variety, and Screen International.

The counted reviews so far are not enough to form a critical consensus, another feature of Rotten Tomatoes that determines whether a film is "certified fresh," or "rotten." However, more reviews are expected in the coming weeks, as "BuyBust" is set to be released in North America on August 10, via distributor Well Go USA.
