They are returning as strings because in the database I believe they are strings, and the fetchObject/fetchAll function does not automatically convert from column to object (not that I know rs).

You have 2 options, do the conversion after the fetchObject, or use a class that the constructor does this transparently for you.

Option 1 - After fetchObject 

function showContents($tb, $token = 0) {
  // Busca um conteudo no bd de acordo com o token
  if ($token) {
    $showContents = $this->pdo->connect()->prepare("SELECT * FROM $tb WHERE token=:token");
    $showContents->bindParam(":token", $token, PDO::PARAM_STR);
    $showContents->execute();
    if ($showContents->rowCount() == 1) {
      $obj = $showContents->fetchObject();
      $obj->genre = json_decode($obj->genre);
      $obj->cast  = json_decode($obj->cast );
      return $obj;
    } else {
      return false;
    }
  } else {
    // Busca todos os conteudos da tabela no bd
    $showContents = $this->pdo->connect()->query("SELECT * FROM $tb");
    $objs = $showContents->fetchAll(PDO::FETCH_OBJ);
    foreach($objs as &$obj) {
      $obj = $showContents->fetchObject();
      $obj->genre = json_decode($obj->genre);
      $obj->cast  = json_decode($obj->cast );
    }
    unset($obj);
    return $objs;
  }
}

Option 2 - Using a class 

class Filme {
  public $id;
  public $title;
  public $year;
  public $age;
  public $time;
  public $genre;
  public $cast;
  public $director;
  public $description;
  public $source;
  public $principalThumb;
  public $type;
  public $token;

  // construtor é chamado depois das propriedades serem preenchidas pelo fetchObject e fetchAll, por isso funciona
  function __construct() {
     $this->genre = json_decode($this->genre);
     $this->cast  = json_decode($this->cast );
  }

}

function showContents($tb, $token = 0, $class_name = "stdClass") {
  // Busca um conteudo no bd de acordo com o token
  if ($token) {
    $showContents = $this->pdo->connect()->prepare("SELECT * FROM $tb WHERE token=:token");
    $showContents->bindParam(":token", $token, PDO::PARAM_STR);
    $showContents->execute();
    if ($showContents->rowCount() == 1) {
      $obj = $showContents->fetchObject($class_name);
      return $obj;
    } else {
      return false;
    }
  } else {
    // Busca todos os conteudos da tabela no bd
    $showContents = $this->pdo->connect()->query("SELECT * FROM $tb");
    $objs = $showContents->fetchAll(PDO::FETCH_OBJ, $class_name);
    unset($obj);
    return $objs;
  }
}

// e na hora de chamar a função, passe o nome da classe
$filme10 = showContents('TBL_FILMES', 10, 'Filme');
