This one brings back memories of classics like The Parent Trap, with a gender twist. Amanda Davin plays Martin and Julia, both from broken families and decide to swap lives. It's a funny, entertaining movie with some really funny moments. Especially the wedding scenes are particularly funny. Martin's huge grandmother is hilarious.
Amanda does a very good acting job playing a girl and a boy, very distinctively. I also liked the refreshing music, and production design is great.
This has lots of international potential, for a Scandinavian movie. It tells a universal story - if you get the chance, possibly with your kids - go see it.
