SO. MUCH. CONFUSION!!!

let movieDictionary = ["Spectre": ["cast": ["Daniel Craig", "Christoph Waltz", "LÊa Seydoux", "Ralph Fiennes", "Monica Bellucci", "Naomie Harris"]]]

var leadActor: String = ""

// Enter code below


if let actor = movieDictionary["cast"] {
   leadActor = // What the heck do I put here? I know how to reference an array item, but how do I reference an array item inside of a key inside of a dictionary... wtf? MAJOR CONFUSION!!!
}

As stated above... I have NO CLUE what he wants. I am trying to get the "Daniel Craig" Value outside of the array... but HOW do you do that while its nested inside of two other types??? I feel again like a crucial piece of info was omitted. :/
