Rails3 routing error

My scenario: Movies have reviews, reviews have comments.

Movie model:

has_many :reviews

Review model:

has_many :comments
belongs_to :movie

Comment model:

belongs_to :review

Routes:

resources :movies do
  resources :reviews do
    resources :comments
  end
end

Comments controller:

def create
  @movie = Movie.find(params[:movie_id])
  @review = Review.where(:movie_id => @movie.id)
  @comment = @review.comments.create(params[:comment])  // Line 5
  redirect_to movie_path(@movie)
end

Comment view:

<%= form_for([@movie, r, r.comments.build]) do |f| %>
  <div class="field">
    <%= f.text_area :body %>
  </div>
  <div class="actions">
    <%= f.submit "Submit" %>
  </div>
<% end %>

The error that I get is:

NoMethodError (undefined method `comments' for #<ActiveRecord::Relation:0x007ff5c5870010>):
app/controllers/comments_controller.rb:5:in `create'

Can somebody please tell me what I'm doing wrong?

Thanks in advance..

Review.where returns a list of reviews, what you want is an instance

@review = Review.where(:movie_id => @movie.id).first

or

@review = Review.find_by_movie_id(@movie.id)

Make sure to handle nil case.
