    }

    @Override
    public void onItemSelected(Presenter.ViewHolder itemViewHolder, Object item, RowPresenter.ViewHolder rowViewHolder, Row row) {

        if (item instanceof Movie) {
            Movie movie = (Movie) item;
            // Check if the movie has a backdrop
            if(movie.getBackdropPath() != null) {
                mBackgroundManager.loadImage(HttpClientModule.BACKDROP_URL + movie.getBackdropPath());
            } else {
                // If there is no backdrop for the movie we just use a default one
                mBackgroundManager.setBackground(ContextCompat.getDrawable(getActivity(), R.drawable.material_bg));
            }
