Collections are a convenient way of grouping sequels together on TMDb. While sometimes controversial, collections are not intended to be a way of grouping movies of the same "universe", person or theme. For that, we recommend creating a list. Like this. Here's a quick run through of the basic rules.
- Sequels are generally the only valid criteria for collections. Please use lists to group films based on any other criteria
- Collections are not mirrors of DVD or Blu-ray box sets, use lists to imitate box sets
- Films cannot be in more than one collection at a time, and collections cannot be nested
Creating a New Collection
To create a new collection, you have to first create a movie. Once the movie has been created, head into the "Primary Facts" edit area and convert the item to a collection under the "Convert to Collection?" option. Save it and the page should reload as a collection.
Adding a Movie to a Collection
Once a collection exists (see above) you can go into the edit section of the collection and add new parts from within the "Parts" category. Movies can only belong to a single collection.
