Django - Click on link won't redirect me to the page unless i right click and open in new tab

I'm fairly new to django and I'm working on a project for some reason clicking on my links won't redirect me to the desired page, nothing happens, but i cant open it bu right click > open in new tab here is my template

index.html:

<ul class="list">
      {% for movie in all_movies %}
        <li>
          <img src="{{ movie.poster }}" alt="" class="cover" />
          <a href="{% url 'detail' movie.id %}"><p class="title">{{ movie.title }}</p></a>
          {% for genre in movie.genre.all %}
            <p class="genre">{{ genre.genre }} | </p>
          {% endfor %}
        </li>
      {% endfor %}
</ul>

views.py :

def detail(request, movie_id):
   movie = get_object_or_404(Movie, pk=movie_id)
   return render(request, 'movies/detail.html', {'movie': movie})

urls.py :

urlpatterns = [
   # /movies/
   url(r'^$', views.index, name='index'),
   # /movies/id/
   url(r'^(?P<movie_id>[0-9]+)/$', views.detail, name='detail'),
]

i can't find what's wrong with my code, any help would be appreciated!
