Android (Java) RetroFit 2 | TMDB Movie API | Class name unfortunately determines if API call is successful

Question

*Using RetroFit 2 in an Android project (Java), I am calling the famous TMDB API server for movies, genres and trailers. For these entities, I made Java objects: Trailer, Genre, movie. As you can see, the movie class is without a capital M. It appears that the movie object does not get instantiated if the class name is set to Movie. The API response is successful however. Whenever I change the class name back to movie, the API call instantiation works again.

Question: how to make Retrofit instantiate the movie without considering what the actual Java class name is?

Class definition that makes the Retrofit call work:

public class movie implements Serializable {


    // API attributes
    @SerializedName("id")
    @Expose
    private int id;
    @SerializedName("title")
    @Expose
    private String title;
    @SerializedName("release_date")
    @Expose
    private String releaseDate;
    @SerializedName("poster_path")
    @Expose
    private String imageURL;
    @SerializedName("original_language")
    @Expose
    private String language;
    @SerializedName("overview")
    @Expose
    private String description;
    @SerializedName("vote_average")
    private float avgRating;

Class definition that makes the Retrofit call not work (class name changed), even though the actually networking is successful:

public class Movie implements Serializable {


    // API attributes
    @SerializedName("id")
    @Expose
    private int id;
    @SerializedName("title")
    @Expose
    private String title;
    @SerializedName("release_date")
    @Expose
    private String releaseDate;
    @SerializedName("poster_path")
    @Expose
    private String imageURL;
    @SerializedName("original_language")
    @Expose
    private String language;
    @SerializedName("overview")
    @Expose
    private String description;
    @SerializedName("vote_average")
    private float avgRating;

Retrofit call (more details are not relevant, since there is always a successful response

 public void retrieveMovies() {
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .build();

        TMDBApiService service = retrofit.create(TMDBApiService.class);
        Call<NowPlayingMoviesResponse> call = service.retrieveMovies(API_KEY, language, 1);

        call.enqueue(new Callback<NowPlayingMoviesResponse>() {
            @Override
            public void onResponse(@NonNull Call<NowPlayingMoviesResponse> call,
                                   @NonNull Response<NowPlayingMoviesResponse> response) {

Class that packages movies

public class NowPlayingMoviesResponse {

    @SerializedName("results")
    private List<movie> results;

    public NowPlayingMoviesResponse(List<movie> results) {
        this.results = results;

    }

    public void setResults(List<movie> results) {
        this.results = results;
    }

    public List<movie> getMoviesResult() {
        return results;
    }
