input: Write a python function to create a list of Movie objects and filter those with a rating above a given threshold.
  ```python
  class Movie:
      def __init__(self, title, release_year, rating):
          self.title = title
          self.release_year = release_year
          self.rating = rating
  
  def filter_movies(movies, threshold):
      return [movie for movie in movies if movie.rating > threshold]
  
  # Test
  movies = [
      Movie("The Godfather", 1972, 9.2),
      Movie("The Dark Knight", 2008, 9.0),
      Movie("Pulp Fiction", 1994, 8.9),
      Movie("Fight Club", 1999, 8.8)
  ]
  
  assert [movie.title for movie in filter_movies(movies, 9.0)] == ["The Godfather"]
  assert [movie.title for movie in filter_movies(movies, 8.9)] == ["The Godfather", "The Dark Knight"]
  assert [movie.title for movie in filter_movies(movies, 8.5)] == ["The Godfather", "The Dark Knight", "Pulp Fiction", "Fight Club"]
output: class Movie:
      def __init__(self, title, release_year, rating):
          self.title = title
