Symfony2: how to show valuables from different tables?

I'm trying to create an website in Symfony in which I have a database with Movies. This how it looks like:

/**
 * Game entity.
 */

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Class Movie.
 *
 * @ORM\Table(name="movies")
 * @ORM\Entity(repositoryClass="AppBundle\Repository\Movie")
 */
class Movie
{
/**
 * Id.
 *
 * @ORM\Id
 * @ORM\Column(
 *     type="integer",
 *     nullable=false,
 *     options={
 *         "unsigned" = true
 *     }
 * )
 * @ORM\GeneratedValue(strategy="IDENTITY")
 *
 * @var integer $id
 */
private $id;

/**
 * Title.
 *
 * @ORM\Column(
 *     name="title",
 *     type="string",
 *     length=255,
 *     nullable=false
 * )
 *
 * @var string $title
 */
private $title;

/**
 * Notes.
 *
 * @ORM\Column(
 *     name="notes",
 *     type="text",
 *     nullable=true
 * )
 *
 * @var string $notes
 */
private $notes;

  /**
 * Genres array
 *
 * @ORM\ManyToOne(targetEntity="Genre")
 * @ORM\JoinColumn(name="genre_id", referencedColumnName="id")
 * )
 *
 * @var \Doctrine\Common\Collections\ArrayCollection $genres
 */
   protected $genres;


/**
 * Constructor.
 */
public function __construct()
{
    $this->tags = new \Doctrine\Common\Collections\ArrayCollection();
}

/**
 * Get id.
 *
 * @return integer 
 */
public function getId()
{
    return $this->id;
}

/**
 * Set id.
 *
 * @param integer $id
 */
public function setId($id)
{
    $this->id = $id;
}


/**
 * Set title.
 *
 * @param string $title
 */
public function setTitle($title)
{
    $this->title = $title;
}

/**
 * Get title.
 *
 * @return string 
 */
public function getTitle()
{
    return $this->title;
}

/**
 * Set notes.
 *
 * @param string $notes
 */
public function setNotes($notes)
{
    $this->notes = $notes;
}

/**
 * Get notes.
 *
 * @return string 
 */
public function getNotes()
{
    return $this->notes;
}


/**
 * Add genres
 *
 * @param \AppBundle\Entity\Genre $genres
 * @return Movie
 */
public function addGenre(\AppBundle\Entity\Genre $genres)
{
    $this->genres[] = $genres;

    return $this;
}  

/**
 * Set genres
 *
 * @param \AppBundle\Entity\Genre $genres
 * @return Movie
 */
public function setGenres(\AppBundle\Entity\Genre $genres = null)
{
    $this->genres = $genres;

    return $this;
}

/**
 * Get genres
 *
 * @return \AppBundle\Entity\Genre 
 */
public function getGenres()
{
    return $this->genres;
}
}

And each Movie has a Genre:

 /**
 * Genere entity.
 *
 */

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
  * Class Genere.
  *
  * @ORM\Table(name="genere")
  * @ORM\Entity(repositoryClass="AppBundle\Repository\Genere")
  */
 class Genere
{
/**
 * Id.
 *
 * @ORM\Id
 * @ORM\Column(
 *     type="integer",
 *     nullable=false,
 *     options={
 *         "unsigned" = true
 *     }
 * )
 * @ORM\GeneratedValue(strategy="IDENTITY")
 *
 * @var integer $id
 */
private $id;

/**
 * Name.
 *
 * @ORM\Column(
 *     name="name",
 *     type="string",
 *     length=128,
 *     nullable=false
 * )
 *
 * @var string $name
 */
private $name;
/**
 * Get Id.
 *
 * @return integer Result
 */
public function getId()
{
    return $this->id;
}

public function setId($id)
{
    $this->id = $id;
}

/**
 * Set name.
 *
 * @param string $name Name
 */
public function setName($name)
{
    $this->name = $name;
}

/**
 * Get name.
 *
 * @return string Name
 */
public function getName()
{
    return $this->name;
}

Now, my question is: how can I show a genre in movies list? I know how to make a list of movies, but no idea what to use to show genres. My MovieController currently looks like this:

/**
 * List action.
 *
 * @Route("/movie-list", name="movies-list")
 * @Route("/movies-list/")
 *
 * @throws NotFoundHttpException
 * @return Response A Response instance
 */
public function listAction()
{
    $movies = $this->findByStatId(2);
    if (!$movies) {
        throw new NotFoundHttpException('Movies not found!');
    }
    return $this->templating->renderResponse(
        'AppBundle:Movie:index.html.twig',
        array('movies' => $movies)
    );
}

What should I add to be able to show genres? Where? Any advises would be welcome.

You have a mistake in your Genre class. At least in your example, you call it Genere instead of Genre. Second, if a movie should have more than one genre then you should make a many-to-many association, as multiple movies can have the same genre. If a movie can only have one genre, then you have to switch the owning side with Genre (Movie should have Genre (singular), Genre should have Movies (plural))

You already have genres along with $movies variable. You just have to call access genres like this:

{% for genre in movies.genres %}
   {# Access each genre variable here #}
{% endfor %}

movies is a object passed to twig file and it has property genres to access related genres in it.

To access genres on controller:

<?php
    $genres=$movies->getGenres();
    // loop through $genres.
?>

getGenres() will return collection of genres.
