However, the movie's success was short-lived, as it soon found its way onto piracy websites like Moviesda. The movie was leaked online, with users able to download it for free. This not only affected the film's box office performance but also led to a significant loss for the producers.

The controversy surrounding Tamil movie downloads, specifically "Mumbai Express" and Moviesda, highlights the pressing issue of online piracy in the film industry. Piracy not only affects the financial performance of movies but also has far-reaching consequences for the livelihoods of people working in the industry.

Moviesda has been a thorn in the side of the Tamil film industry for years. The website has been accused of providing unauthorized movie downloads, including Tamil films. The website's administrators have been known to upload movies within hours of their release, often in high-quality formats.
