-(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {

    self.selectedMessage = [self.messages objectAtIndex:indexPath.row];
    NSString *fileType = [self.selectedMessage objectForKey:@"fileType"];
    if ([fileType isEqualToString:@"image"]) {

    }
    else {
        PFFile *videoFile = [self.selectedMessage objectForKey:@"file"];
        NSURL *fileUrl  = [NSURL URLWithString:videoFile.url];
        self.moviePlayer.contentURL = fileUrl;
        [self.moviePlayer prepareToPlay];

        //display thumbnail
        AVAsset *videoThumbnail = [AVAsset assetWithURL:fileUrl];
        [AVAssetImageGenerator assetImageGeneratorWithAsset:videoThumbnail];

        //add it to the view controller so we can see it
        [self.view addSubview:self.moviePlayer.view];
        [self.moviePlayer setFullscreen:YES animated:YES]; 
    }

    //Delete Message

        [self.selectedMessage deleteInBackground];
    }
    else {
