Mockito not working on update/create in RESTcontroller

I'm trying to write some tests using Mockito and I managed to write them for findAll and delete operations but for the create and update, they won't work.

@RunWith(MockitoJUnitRunner.class)
public class RentedControllerTest {

    @Mock
    private RentedService rentalService;

    @Mock
    private MovieService movieService;

    @Mock
    private ClientService clientService;

    @InjectMocks
    private RentedController rentalController;

    @InjectMocks
    private MovieController movieController;

    @InjectMocks
    private ClientController clientController;


    @Before
    public void setUp() throws Exception {
        initMocks(this);
    }

    @Test
    public void getMovies() throws Exception {
        List<Movie> movies = new ArrayList<>();
        movies.add(mock(Movie.class));
//        System.out.println(movies.toString());
        when(movieService.findAll()).thenReturn(movies);
////        System.out.println(movieService.findAll().toString());
        MoviesDto response = movieController.getMovies();
        assertEquals("should be 1 movie", 1, response.getMovies().size());
    }

    @Test
    public void updateMovie() throws Exception {
        Movie movie = new Movie(2,"Lotr",0, "dir2", 2003);
        MovieDto movieDto = mock(MovieDto.class);
        System.out.println(movie.toString());
        when(movieService.updateMovie(anyInt(), anyString(), anyInt(), anyString(), anyInt())).thenReturn(movie);
//        Movie m = new Movie();
//        m = movieService.updateMovie(2,"Lotrrrrr",0, "dir2", 2003);
//        System.out.println(m.toString());
        Map<String, MovieDto> map = movieController.updateMovie(2, movieDto);
        System.out.println(map.toString());
        assertEquals("Title should be Lots", "Lotr", map.get("movie").getName());
    }

    @Test
    public void createMovie() throws Exception {
        Movie movie = new Movie(2,"Lotr",0, "dir2", 2003);
        MovieDto movieDto = mock(MovieDto.class);
        when(movieService.createMovie(anyInt(), anyString(), anyInt(), anyString(), anyInt())).thenReturn(movie);
        Map<String, MovieDto> map = movieController.createMovie(movieDto);
        assertEquals("Title should be Lotr", "Lotr", map.get("movie").getName());
    }

    @Test
    public void deleteMovie() throws Exception {
        ResponseEntity response = movieController.deleteMovie(1);
        assertEquals("Http status should be OK", HttpStatus.OK, response.getStatusCode());
    }
}

So the line "when(movieService.update....) work's just fine. I tested it with the write lines as you can see in the code and it works. The problem is here

Map<String, MovieDto> map = movieController.updateMovie(2, movieDto);

I gives me NullPointerException inside that method. The method looks like this:

@RequestMapping(value = "/movies/{movieId}", method = RequestMethod.PUT, consumes = CatalogMediaType.API_JSON)
    public Map<String, MovieDto> updateMovie(@PathVariable final Integer movieId,
                                             @RequestBody final MovieDto movieDto) {
        log.trace("updateMovie: movieId={} movieDto={}", movieId, movieDto);

        Movie movie = movieService.updateMovie(movieId, movieDto.getMovie().getName(), movieDto.getMovie().getNumberofrentals(), movieDto.getMovie().getDirector(), movieDto.getMovie().getYear());

        Map<String, MovieDto> movieDtoMap = new HashMap<>();
        movieDtoMap.put("movie", new MovieDto(movie));
        log.trace("updateMovie: movieDtoMap={}", movieDtoMap);

        return movieDtoMap;
    }

The application itself works perfectly, the problem arises only when runing the mockito tests.

I don't really understand what the problem is if the findAll and delete work just fine... Any ideas?
