'Must Have Been Love' (its Norwegian title, 'En Som Deg', would more accurately translate as 'Someone Like You'), opens in İstanbul as three holidaying girls from Finland meet three holidaying boys from Norway. One each from the two groups - Kaisa and Jakub, respectively - hit it off rather well, although Jakub is mysteriously reluctant to explain why he dumped his fiancée. But the boys are leaving the next day, so the spark between the two never has the chance to, erm, ignite.

Some time later Kaisa, having secured employment in Norway, is wandering around an Oslo supermarket when she spots someone she thinks is Jakub: apart from a different hairstyle, moustache and one of those ludicrous little lip-beards, the resemblance is uncanny. However, it's *not* Jakub: this chap says he doesn't recognise Kaisa and denies ever having been in İstanbul. But he is attracted to her and the pair begin a relationship - indeed, Anders (for that is his name) follows Kaisa to Helsinki when she has to return to her native country and the pair set up home together. But then cracks start to appear in the relationship and it becomes apparent that Anders isn't exactly who Kaisa imagined him to be. Lucky for her she's met Jakub again...

After the film's showing at the 2013 London Film Festival I was walking behind two Norwegian women who had also seen it - my Norwegian isn't good enough to understand exactly what they were saying, but the tone of disbelief in their voices said it all. A British woman talking to her friend was even more understandable: "Actually, that girl really p****d me off" she commented (expletive deleted to get around IMDb's rather puritanical 'prohibted words' list!) The film certainly tries the viewer's patience: it starts off as a rather sweet and chaste romance, then veers into a sort of mystery (is Anders really Jakub? And what's this business with him standing in the road in his pants - is it a dream, or did it really happen?) The big reveal of Anders' identity leads the viewer to question Kaisa's sanity and undermines the entire film.

On the other hand, the acting is okay: Espen Klouman Høiner, as Jakub/Anders, manages to create two distinct but different characters; Pamela Tola as Kaisa is perfectly competent and very pretty.

So: man given to nocturnal wanderings in his pants? Check. Another man who refuses to discuss his former relationship? Check. Woman who imprints the features of might-have-been boyfriends onto other men? Check. This film is psychos in love!

Is love really based upon wanting something so hard that you really decide yourself what you want out of it? That's my thought while watching this Norwegian/Finnish film by Norwegian director Eirik Svensson.

This movie is so romantic, that it's almost unbelievable. Got to be a great for couples in love to watch. Not only is the start of the film taking place in Instanbul under very pleasant holiday weather and romantic circumstances, but what is impossible to miss out on, is that it's so naturally played by all the actors. The chemistry is amazing.

What it really interesting, is that it's a double take on a love story, by some freak luck. It's also a great take on person sons meeting accidentally, feeling chemistry. A contact which may never would have taken place if it weren't for Kaisa's brave first steps of conversation. The film relays heavily on fantasy of the mind as well as imagination and the need to feel loved. It's also an inspiration to follow up your dreams, and never compromise on your inner feelings. And how is it possible to go to work like everything's normal, when you're head over heels in love?

Debuting feature film director Eirik Svensson has made a great little film as a debut, which really is a good take on a starting romances. I find the acting very natural and realistic. Simple forward meeting of a couple of shy, normal humans. Beautifully filmed also on a small budget, and the story is both written (with Jyrki Vaisanen) and directed by a guy we obviously will hear much more from.

It's really love at first sight between Norwegian Jacob and Finnish Kaisa, meeting at his final day of holiday in Istanbul. The next day ho goes back to Norway, but Kaisa can't forget him. Later on she moves from Helsinki to Oslo, and coincidentally he recognizes Jacob again in a supermarket. But is it Jacob? Doesn't he recognize her? Doesn't he want to admit they have met? It builds up to be a predicament.

The chemistry between Pamela Tola and Espen Klouman-Høiner is showing great acting. It's the first time I see her in a film, but he is always very good. For many it'll be Joachim Trier's "Reprise", which was widely critically acclaimed. Here he is playing to different guys, which resembles each other. He does remarkably well. What a talented young actor!

The film is 98% spoken in English, due to the two languages being so different that they have English as a second language in both countries. It'll work well internationally.

The film has good drive until it stalls a bit mid way through. Still very romantic, but it's more likely to make you fall off then, if you're not the romantic type. I'm not a great fan of romantic films, but still the chemistry here saves the day!
