iOS Enumerations and Optionals in Swift Introduction to Optionals Nil Values in Collections

I can't figure out how it wants this nested optionals

i have tried:

if var movie = movieDictionary["Spectre"], var castList = movie["cast"] { var leadActor = list[0] } and : if var movie = movieDictionary["Spectre"], var castList = movie["cast"], var leadActor = castList[0]

and none of these have worked. When trying the first one it tells me that something isn't right with the array subscript. When trying it the other way, it tells me that I don't have the right variable name or something.

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

var leadActor: String = ""

// Enter code below
if var movie = movieDictionary["Spectre"], var castList = movie["cast"] {
  var leadActor = list[0]
}

Never mind. I was stupid and didn't notice that a variable of leadActor was already created in the challenge
