I think it's clear that we are responding to this in case it's true. If it's not and they have a better theme, great.
If you are complaining about a lack of humour you are right though. I don't see the pointe in choosing the theme "movie". Unless you mean the hilarity of having a theme that's already used over and over without it being a theme. There is absolutely zero inspiration in this.
Looking at the programs thread, his season's free dances include the soundtracks of: Umbrellas of C, Les Miserables, Phantom of the Opera, Rocky, Interstellar, Mixed soundtracks by Guignard and Fabbri, West Side Story, The Perfume, Aladdin, Addams Family, Schindler's List, James Bond, Game of Thrones, Memoirs of a Geisha, Chicago, Lord of the Rings, Matrix, Moulin Rouge...
Maybe if they disallow musicals among the movies we can erase some of the usual suspects, but I absolutely fail to see the necessity of a topic "movies".
