  +Until now, we have created a GraphQL API to retrieve film data.
   We now want to enable the clients to retrieve the `Hero` data of the `Film`.
   
   Add the following to our `FilmResource` class:
  
positive.code: }
  ----
  
  <1> `@GraphQLApi` annotation indicates that the CDI will be a GraphQL endpoint
  <2> `@Query` annotation defines that this method will be queryable with the name `allFilms`
  <3> Documentation of the queryable method
  
  
negative.code: ----
  
  WARNING: Notice how we have excluded the value in the `@Query` annotation.
  Therefore, the name of the query is implicitly set as the method name
  excluding the `get`.
  
  This query will allow the client to retrieve the film by id.
  
  Enter the following into `GraphiQL` and make a request.
