After years apart, old friends Adam Franklin (Ashton Kutcher) and Emma Kurtzman (Natalie Portman) reconnect through mutual friend Patrice (Greta Gerwig). Their meeting is fleeting, but months later, after Adam's father Alvin (Kevin Kline) runs off with his ex-girlfriend (Ophelia Lovibond), the depressed aspiring screenwriter invites Emma to his apartment.
The pair's relationship changes forever, when, despite their history and better judgement, they end up sleeping together. Busy doctor Emma doesn't believe in monogamy and is more than happy to keep their arrangement casual, but as Adam begins to fall for her, their idea of a 'no strings attached' relationship quickly unravels.
One of a few 'friends with benefits' tales doing the rounds (this film was due to be called just that until the Justin Timberlake/Mila Kunis vehicle snapped up the heading), No Strings... derives its spark from its brash, modern approach to sex and relationships.
Despite its proudly unromantic set-up, Ivan Reitman's film soon inevitably reverts to dealing with matters of the heart. Kutcher and Oscar winner Portman do provide some edge, however, creating crackling chemistry, while the likes of Kline and Gerwig provide solid support. While it might not revolutionise the rom-com, the gorgeous leads and some fun banter make No Strings Attached an endearing addition to the genre.
