Based on the classic novel by Guðrún Helgadóttir, this film is still very funny and has wide appeal to audiences of all ages. It is somewhat dated, but that only serves to make it funnier. The film covers the adventures of twin brothers Jón Oddur and Jón Bjarni, who get up to a lot of mischief - not Home Alone style, but rather real things that real kids might do.
