if let movie = movieDictionary["Specture"], let cast = movie["cast"]{ leadActor = cast[0] }

Why is throwing an error?

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

var leadActor: String = ""

// Enter code below
if let movie = movieDictionary["Specture"], let cast = movie["cast"]{
    leadActor = cast[0]
}

You misspelled Spectre as Specture. Just fix that and it works perfectly fine.
