i had the same problem - 3 hrs into the tutorial and thought i hit a road block...

However a quick search on symfony website (https://symfony.com/doc/current/templates.html#creating-templates) shows you need to pass the dynamic variables with the render function

So if you followed along with the tutorial - in your MoviesController file you would have created a $movies DB query - something like $movies = $repository->findAll()

You need to pass that along with the render method like this... return $this->render('movies/index.html.twig', ['movies' => $movies,]);

Seems strange that this is missing from the MoviesController file in git repo

Hope that helps.
