@Nada is totally right, I used to watch Bud Spencer and Terence Hill´s flicks in my childhood and I used to enjoy them a lot jajaja. Dubbed in Spanish the voices also don´t match the actors´ lips but I didn´t use to care for that.
This is Bud Spencer´s funniest scene ever :)
Bom bo bo bom bo bo bom bo bo bom
The large bearded man is definitely dubbed. The original actor may have done his own dubbing in English, but he has a British accent.
The blond guy sounds Danish to me. And the woman sounds African, but I don't know dialects so I can't be specific.
