I think its prequel, "Speedy Gonzales - Noin 7 veljeksen poika" (Speedy Gonzales, son of about 7 fathers) is a bit better as it has a giallo subplot in it. The "& fathers" are a classic finnish tale.
Anyway both movies are easily available on DVD by Finnkino...both separate edition or in a 4 DVD Box Set along with other titles of this actor whoise I forgot the name, but he's the most famous comic actor in Finland.
There are only 2 more western shot in Finland: "Villin pohjolan kulta" (The legend of the northern gold, 1963, available on DVD by Finnkino) and its sequel "Villin pohjolan salattu laasko" (not available on DVD yet). They are copies of classic american westerns, with a sort of Calamity Jane and a lot of classical humor and good feelings in it.
Also I found Hirtamattomat a bit...how to say....upsetting...though it's a comedy, the direction is somehow autorish like every finnish movie ever shot...don't know, I have a personal issue against finnish cinema.
