Why does it keep saying "Make sure you are retrieving the string at index 0 in the nested array"

Hello!

I am stuck here because it keeps saying to "Make sure you are retrieving the string at index 0 in the nested array" but isn't that what I am doing at the end by declaring that leadActor = mainActor[0]?? if the string that I need to pull from the nested array is in the first position isn't that at index position 0??

Thanks!!

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 movieTitle = movieDictionary["Specter"], let mainActor = movieTitle["cast"]{
    leadActor = mainActor[0]
}

You have a typo with "er" instead of "re"

movieDictionary["Specter"]

should be

movieDictionary["Spectre"]
