Changes in my view model are not showing

[thm1d]

My new added code also edited code are not updating in my webpage.
Here is my view model function :

public function movie()
    {
    	return collect($this->movie)->merge([
    			'poster_path' => 'https://image.tmdb.org/t/p/w500/'. $this->movie['poster_path'],
    			'release_date' => \Carbon\Carbon::parse($this->movie['release_date'])->format('M d, Y'),
    			'genres' => collect($this->movie['genres'])->pluck('name')->flatten()->implode(', '),
    			'runtime' => date('g\h i',mktime(0,$this->movie['runtime'])),
    			'crew' => collect($this->movie['credits']['crew'])->take(2),
    			'cast' => collect($this->movie['credits']['cast'])->take(5),
    			'backdrops' => collect($this->movie['images']['backdrops'])->take(3),
    			'release_year' => substr($this->movie['release_date'],0,4),
                        'reviews' => collect($this->movie['reviews']['results'])->take(5),
                        'author' => collect($this->movie['reviews']['results'][0]['author_details']),
    		])->dump();
    }

controller :

public function show($id)
    {

        $movie = Http::withToken(config('services.tmdb.token'))
            ->get('https://api.themoviedb.org/3/movie/'.$id.'?append_to_response=credits,videos,images,reviews')
            ->json();

        if ($movie['imdb_id'] != "") {
            $imdb = Http::get('http://www.omdbapi.com/?i='.$movie['imdb_id'].'&apikey='.$apikey)
            ->Json();
        }
        else {
            $imdb = $movie;
        } 
        //dump($movie);
        $viewModel = new MovieViewModel(
            $movie, 
            $imdb,
        );
        return view('movie.show', $viewModel);
    }

Here I have added the 'review' and 'author' field but not getting it. I also changed 'backdrops' field to take(3) from take(9) but no change. Here is what I am getting :
