First, I should confirm what the Navarasa project is. I remember it's a collection of short films by 9 directors, each based on a different emotion. "Toxic" is one of them, focusing on anger. The user wants the full film in MP4, possibly for free. But I need to be cautious about promoting illegal downloads.

Also, the tags mention lifestyle and entertainment, so maybe the user is interested in film for personal use. I should emphasize supporting creators and respecting intellectual property. It's important to highlight the consequences of piracy and guide them toward legal sources. If the film is available on a streaming service, that's a safer bet. If not, maybe suggest purchasing from legitimate stores like iTunes or Google Play Movies.

Additionally, the user might not be familiar with the legal distribution channels, so providing a clear path without directing to potentially illegal sites is key. Making sure the response is helpful and informative while upholding ethical standards and legal compliance.
