I'm for the Hippopotamus (Italian: Io sto con gli ippopotami) is a 1979 Italian adventure comedy film directed by Italo Zingarelli and starring the film duo of Terence Hill and Bud Spencer.
[1] The film focuses on the rivalry between two cousins, with one of them intentionally undermining the other's safari expeditions.
It turns out that Spencer's character is none too honest, either, since he gives his tourists rifles loaded with blanks so they can't hurt each other or the animals.
The two have to team up to stop a villain, with plenty of comedy, eating, and mild violence.
As with many other Spencer & Hill films, its soundtrack and theme song "Grau Grau Grau" (both composed and performed by Walter Rizzati, with Spencer himself providing lead vocals on the song) became very popular in Italy at the time of the film's release, and are still popular among the duo's international fan base.
