Getting variable outside of if-statement

How to get that constant named "b" out of the if-statement and assign it to leadActor

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

var leadActor: String = ""

// Enter code below

if let a = movieDictionary["Spectre"], let b = actor["cast"]{
    print(b[0]) //This gets me "Daniel Craig"
}else {print("No such directory")}

Close, but they don't want you to print it, and they wanted nested optional binding if let statements:

if let a = movieDictionary["Spectre"] {
  if let b = a["cast"] {
    leadActor = b[0] 
  }else {
    print("No such directory")
