What you need before you start

Collection builders need a clear list of titles, a place to review title details, and a decision about how organized metadata will move into the library workflow.

Prepare the movie and show lists that will be used for collection building, and decide which titles need review before they are added to a collection.

Check how titles are identified across the tools in the workflow, because a title match needs to point to the correct movie or show before metadata work continues.

Keep notes about the sources used for collections and any titles that need manual checking. A simple review process helps avoid adding the wrong title or missing important details.

Choose whether the workflow needs a tool that turns lists into Radarr or Sonarr sources, a manual collection method, or another approach.

Step by step

Gather the public lists or title sources that contain the movies and shows for the collection.

Review the titles and remove entries that are not part of the collection goal. Check names, versions, and title matches before moving them into the library workflow.

Choose where the title information should go. A collection builder can use a list-based tool, a manual process, or another method that matches the way the library is managed.

Check each title match before adding it to a collection. If a title cannot be matched correctly, keep it aside for review instead of forcing the wrong entry into the collection.

Keep the collection source organized so future changes are easier to review. A stable source list can help when titles are added, removed, or updated.

Review the finished collection and confirm that the titles, artwork, and details shown in the library match the intended collection.

Tools that can do it

Watcharr is made by the team that publishes this site. Watcharr lets a collection builder paste a public IMDb list and get a link for Radarr with the movies and a link for Sonarr with the shows. ^[1]

Each Watcharr link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. ^[1] A bookmark clicked inside Radarr or Sonarr adds the list using that app's API key without sending it anywhere else. ^[1]

Watcharr accepts public IMDb watchlists or lists from the desktop site, phone site, or IMDb's other-language pages. ^[1] The links are built from the IMDb list's id, so the same list always gives the same two links. ^[1]

A manual list can work when collection builders want direct control over each title. Before choosing a tool, check how it handles title matching, list updates, and the movement of metadata into the library workflow.

Watcharr looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it cannot match, and tells collection builders which ones it skipped. ^[1] The page shows list covers in a row, and each cover opens TMDB plot, genres, rating, backdrop, and trailer details. ^[1]

Common mistakes to avoid

Avoid adding titles before checking that the title match is correct. A wrong match can place the wrong movie or show into a collection.

Avoid keeping collection sources without clear notes. A collection is easier to manage when the source list and review decisions are easy to follow.

Avoid choosing a tool without checking how it handles updates, title matching, and library connections. The right workflow depends on how the collection builder manages titles.

Avoid skipping failed title checks. If a tool reports missing matches or review items, those entries need attention before the collection is considered complete.
