MPMoviePlayer using Swift for Ribbit app

I'm trying to learn Swift by modifying the Ribbit app to Swift code. I want to allow the user to preview the video they take before they send it to their friends, but I can't get an MPMoviePlayer to play a preview of the captured video file. I've tried to get it to work a number of different ways, but here is my most recent code. It seems pretty straightforward, but for whatever reason the MPMoviePlayer won't appear or play.

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject])
    {
        videoUrl = info[UIImagePickerControllerMediaURL] as NSURL

        var player = MPMoviePlayerController(contentURL: videoUrl)
        player.prepareToPlay()
        self.view.addSubView(player.view)
        player.setFullscreen(true, animated: true)
        player.play()
    }

Edit

After some further tinkering, I think the problem lies within the self.view.addSubView(player.view) method. The imagePicker is on a custom overlay nib, and then I'm trying to put the moviePlayer on top of that I believe? Still not sure what the solution is, but we're getting there.
