PHP PHP & Databases with PDO PDO Database Security Cleanup & Final Steps

$film returns array for me, not boolean. Code looks identical except I use exit(), not die(). Any ideas?

My var_dump($film) returns an array with the individual movie's full data, not a boolean like in the video. I cannot figure out why. Here is the code:

<?php

require_once('database.php');

if (!empty($_GET['id'])) {
  $film_id = intval($_GET['id']);

  try {
    $results = $db->prepare('select * from film where film_id = ?');
    $results->bindParam(1, $film_id);
    $results->execute();
  } catch(Exception $e) {
      echo $e->getMessage();
      exit();
  }

  $film = $results->fetch(PDO::FETCH_ASSOC);
var_dump($film);
}



?>

    } else {
      echo 'Sorry, no film was found with the provided ID.';
    }
  ?>
  </h2>
</body>

</html>

And the database.php:

<?php

// Remove error code prior to production.
ini_set('display_errors', 'On');

try{
  $db = new PDO('sqlite:./database.db');
  $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(Exception $e) {
  echo $e->getMessage();
  die();
}


?>

I figured it out. I was entering a valid id, which returned the data properly. When I entered an invalid value I got the false as in the video.
