For the fans of Abatantuono's first period this is a classic. The film is not completely focused on his character (as in Attila flagello di Dio, Viulentemente mia or other glorious titles), but still we can find in it some of his best gags ever: when he flies out of the hotel's balcony (...svulazzo!) and when he states he is able to mentally communicate with seafood. The story is about many different unlikely characters that find themselves in the same hotel at the same time (classic setting). The movie is really stupid, and I won't recommend it to anyone who doesn't know exactly the kind of movie is gonna watch, but as I previously said, if you love the trash Abatantuono, this is a must. Celentano also plays a precious role as the hotel manager: his silent weird looks fit perfectly with his character. In general I think that underground classics of Italian cinema such as Grand Hotel Excelsior are way too much under estimated, considered too the huge number of fans and real lovers they find amongst the best Italian youth. If you like stupid and dumb movies, watch it!
