How to retrieve value of array element which is inside of a dictionary, in swift?

Question

I was able to get a movie selection from Rotten Tomatoes, however, the JSON returned has an array inside of a dictionary, which I'm not familiar with. I have tried this, but it returns nil:

println(moviesDictionary["movies"]?.title)

The Code:

class ViewController: UIViewController {

    private let apiKey = "notGonnaTellYa"

    override func viewDidLoad() {
        super.viewDidLoad()
        let baseURL = NSURL(string: "http://api.rottentomatoes.com/api/public/v1.0/lists/movies/")
        let inTheatersURL = NSURL(string: "in_theaters.json?apikey=\(apiKey)", relativeToURL: baseURL)

        let sharedSession = NSURLSession.sharedSession()
        let downloadTask: NSURLSessionDownloadTask = sharedSession.downloadTaskWithURL(inTheatersURL!, completionHandler: { (location: NSURL!, response: NSURLResponse!, error: NSError!) -> Void in

            if (error == nil) {
                let dataObject = NSData(contentsOfURL: location)
                let moviesDictionary: NSDictionary = NSJSONSerialization.JSONObjectWithData(dataObject!, options: nil, error: nil) as NSDictionary

                println(moviesDictionary["movies"]?.title)
            }

        })

        downloadTask.resume()

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

Try saving moviesDictionary["movies"] in an array, an then access it as you're used to.
