    Observable<Response<Movies>> responseObservable = tmdbService.getMovies(400);
    responseObservable .subscribeOn(Schedulers.newThread())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Subscriber<Response<Movies>>() {
                @Override
                public void onCompleted() {

                }

                @Override
