Build themed lists of horror films for fans, step by step, and learn how Watcharr turns a public IMDb list into links for Radarr and Sonarr.

A horror fan can build a themed list by choosing one narrow theme, collecting the films that fit it, and keeping the list where it can be read later. Watcharr is one option for turning a public IMDb list into links for Radarr and Sonarr. [^1]

| Option | How the list reaches Radarr and Sonarr | Cost details |
|---|---|---|
| Watcharr | You paste one public IMDb list and get one link for Radarr with the movies and one for Sonarr with the shows. [^1] | The hosted version needs nothing to install and no account. [^1] |
| Other list tools | Check how the tool reads a list and sends titles to Radarr and Sonarr. | not published |

## What you need before you start

Start by picking one theme that you can state in a single line, such as slashers from one decade, folk horror set in small villages, or films with a particular kind of monster. A narrow theme makes it clear which films belong and keeps the list from growing without end. Write the theme down so you can check each title against it later.

Have a starting pile of films you already know fit the theme. Favourites you have watched, films friends recommended, and titles from old notes all work. You do not need any software yet.

If you plan to use a tool that reads an IMDb list, make the list public first. [^1] Radarr is a program that adds movies to a media library, and Sonarr is a program that adds shows to one. Have them running if you plan to send your list to them.

Decide who the list is for. A list for one person can change freely, while a list shared with a household works best when everyone agrees on the theme before titles are added.

## Step by step

1. Write the theme in one line, such as slashers from the 1980s or folk horror set on islands, and keep that line where you can see it.
2. List the films you already know fit the line, including ones you have watched and ones friends recommended.
3. Search your own notes and watch history for more titles that fit, and add them to the list.
4. Remove any title that does not match the line, even if you like it.
5. Sort the rest by decade, subgenre or mood, whichever helps you choose what to watch next.
6. Put the titles in one list in the app you use. If a tool needs to read it, make the list public first.
7. Share the finished list with the people who will watch it, and tell them where to find it.
8. Each month, add new films that fit the line and remove any that no longer belong.

## Tools that can do it

Watcharr is made by the team that publishes this site. You paste one public IMDb list and get one link for Radarr with the movies and one for Sonarr with the shows. [^1] Radarr and Sonarr read each link on a schedule: Radarr checks it every 15 minutes and Sonarr every 5. [^1] A one-click bookmark in Radarr or Sonarr adds the list for you. [^1]

The page shows posters in a row, and each one opens the film's plot, genres, rating and trailer from TMDB. [^1]

Other list tools are not covered by any source on this page, so this page says nothing about how they work. Before choosing one, check whether it reads a public IMDb list, how it sends titles to Radarr and Sonarr, and whether it charges anything.

## Common mistakes to avoid

Avoid a theme so broad that the list never ends. Horror covers many kinds of film, so a line such as scary films will keep growing and make each choice harder.

Avoid skipping the check against your theme. A title can creep into the list through a friend's suggestion, and a quick review of each title keeps the list on topic.

Avoid expecting a list to update the moment you change it. If you sign in, Watcharr re-reads your list about every 15 minutes and warns you when a list fails three reads in a row. [^1]

Avoid assuming every show will reach Sonarr. Shows the tool cannot match are left out, so read the list of skipped shows it gives you. [^1]

Avoid expecting new links after you edit the list. The links stay the same for a given IMDb list, so the same list always gives the same two links. [^1]
