How do I refactor to remove the code duplication in this spec:

describe 'TestPlugins'
    describe '.MovieScanner(document)'
        before_each
            MoviePage_loggedIn = fixture("movie_logged_in.html")                // Get logged-in movie page
            MoviePage_notloggedIn = fixture("movie_not_logged_in.html")     // Get non logged-in movie page
            scanner = new MovieScanner()                                                // Get movie scanner
        end

        it 'should scan logged-in movie page for movie data'
            doc = MoviePage_loggedIn            // Get document to scan

            // Unit Tests
            // ------------------------------------------------------------

            // Test movie scanner's functions
            scanner.getMovieTitle(doc).should.eql "The Jacket"
            scanner.getMovieYear(doc).should.eql "2005"

            // Test movie scanner's main scan function
            scannedData = scanner.scan(doc)
            scannedData.title.should.eql "The Jacket"
            scannedData.year.should.eql "2005"
        end

        it 'should scan non logged-in movie page for movie data'
            doc = MoviePage_notloggedIn     // Get document to scan

            // Unit Tests
            // ------------------------------------------------------------

            // Test movie scanner's functions
            scanner.getMovieTitle(doc).should.eql "The Jacket"
            scanner.getMovieYear(doc).should.eql "2005"

            // Test movie scanner's main scan function
            scannedData = scanner.scan(doc)
            scannedData.title.should.eql "The Jacket"
            scannedData.year.should.eql "2005"
        end
    end
end
