Movies without IMDb page

Is there a way to add a film that has no IMDb page, but there is a TMDb and Letterboxd page?
For example this one:
www.themoviedb.org/movie/1217109-demonetized
Adding new titles to IMDb is a nightmare - they reject almost everything without any reason..

The site is set up to link all the information directly from IMDb, so if you're having an issue, I would message Tom directly.
As for TMDB? Never thought to use it. Maybe I should try?
