I need help with optional binding to unwrap a value.

Hey guys,

I am trying to solve this challenge and I really can't figure out what am I doing wrong. Could you please have a look and help me out?

Thanks a lot! (:

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 let movieSpectre = movieDictionary["Spectre"],
let leadActorOfSpectre = movieSpectre["cast"]?[0]
{
    leadActor = leadActorOfSpectre
}

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