The best way to get new movies to start a movie download site would be to contact independent filmmakers and production companies to obtain a license to distribute their films. Depending on the size of the production company, you may need to pay a license fee to distribute their films on your site. Additionally, you can look for public domain films, which are films that are no longer protected by copyright, and can be freely distributed. You can also look for independent filmmakers who are willing to make their films available for free. Finally, you can look for films that are released under Creative Commons licenses, which give you permission to distribute their films with certain conditions.
