This movie (A murder in Hotel Excelsior) is one of successful quaternary of films which comes out of famous TV series Sinful People of the city of Prague (Hrisní lidé mesta prazského), a collection of stories about the crimes and criminologists (with the legendary chief of the investigators Vacátko (Jaroslav Marvan performs him in this full-length pictures too.). Vacátko and his investigators solve a complicated clew of crimes in the world-known Prague hotel (the most serious one is a murder of a faithless wife). It is shaped as the world of high society which is full of degeneracy (alcoholism, promiscuity, gambling). A group of the investigators contrasts with this milieu and this is the font of many comical situations. The performance are excellent. Marvan and the other criminologists (Bláha, Vinklár, Filipovský) are perfect as well as in the other movies from these series, but the most interesting role was given to Milos Kopecký (director of the hotel). Music by Zdenek Liska is also beautiful and its nobleness corresponds with the cheer of the venue.
