Yes like the other reviewer I agree, especially the first half is like an homage to past comedy/slapstick performers. Since the title is close to the Immigrant by Charlie Chaplin, it is not far fetched to say that this is one of them. I have not watched that in ages, so I can't really say what specifically may be a recall, but you can see and tell from how certain scenes go that it feels like a throwback.

Adriano Celentano was quite the known actor in his hey day. And while I reckon for younger audiences it may seem weird, he was also considered a sex idol or at least someone the girls went crazy for. Which I reckon again goes to show us, that if you are a good comedian, looks may not matter that much (at least for women and maybe some men).

So while it's arguably not his best movie, it still is a fun one to watch.
