 Where `$limit` is the maximum number of movies that are retrieved and `$date` the starting date from which movies are retrieved.
 `$limit` is currently set to 100 and `$date` one week before the current one.
 However, because there are multiple publication dates for most movies, the retrieved movies just need to have one publication date that is on or after `$date` for the movie to be included in the result. The `minReleaseDate` is not necessarily the release date displayed in the app, therefore some movies in the app might show up as having been released a long time ago.
