I'm just went back and checked what worked and what didn't.
The initial hash did not work as a symbol and had to be changed to a string for the syntax to work, as mtf mentioned above.
I then responded to the initial screen prompt with "add a movie" and I received the "it looks like you didn't add movies to the hash" notification again with an on screen "Error" notification.
So, the next time I responded to the initial on screen prompt with simply "add" and it worked. So, it does appear as though it was the hash string and on screen response had to be changed in order to work.
I tried it several times and responding with "add a movie" responded with an error notification each and every time.
