Platforms like ShemarooMe, Planet Marathi, and Hoichoi occasionally run free weekend promotions. Keep an eye on their social media channels for "Free for 24 Hours" events.
In some cases, popular Marathi films are aired on public broadcaster Doordarshan for free. While Hapus has not yet been scheduled, you can set an alert. This is the only truly free and legal 24-hour broadcast window available for old Marathi films.
Sometimes, Amazon Prime has promotional offers where you can watch select Marathi movies for free using "Rent or Buy" credits. If you haven't used your Prime trial, that’s another excellent window.
