Posting here for traffic but there is a part of me that wonders if I have dreamt up this film as i've searched for it on 2 film search forums and googled the synopsis repeatedly but have never found it. Also posted about it in Chat on here, but only a few responded and no matches.
So...watched a British film around 2011 and have tried searching for it a few times but have never managed to find it.
Some details may not be accurate and my memories are vague and patchy, but the gist is: Romcom. Group of friends. Two friends are practising to perform a surreal, out-of-water synchronised swimming act at a festival (think it might be Fringe Festival although not totally sure.) There is another couple and the guy plays a fiddle in a band. He ends up sleeping with a mutual friend. I think there is a scene where the guy and the friend he sleeps with share some wine in a bar and I think I remember Portishead playing.
The film may have either been filmed in the 90s or set in this decade from my vague memory of music, clothes and interiors of one of the friend's apartment, which i remember being quite arty.
At the end of the film, there is a marriage and i think that it emerged that the friend who is sleeping with the guy in the band is pregnant.
That's all i have and really hope someone can help as I'm really craving to watch it!
