Hi there! You're either going to love or hate this answer. Your syntax and logic are spot on. You're doing the if let like a pro! So kudos! :thumbsup:

It's your spelling that's a little off. You're getting the movieDictionary for the movie "Specter", but you should be getting it for "Spectre". Note the reversal of the "r" and the "e" in the movie title.

Hope this helps! :sparkles:
