Hi Monzer,

Looks like the leadActor variable is being declared twice instead of once.

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

var leadActor: String = "" // already declared here

// Enter code below
if let mainRole = movieDictionary["Spectre"] , let leadRole = mainRole["cast"]{
  leadActor = leadRole[0]

}

Hope this helps!
