Juno star Michael Cera is returning to the big screen in another teen rom-com, Nick and Norah's Infinite Playlist. The film tells the story of Nick, a geeky bassist in an indie band who is stunned when his recent ex-girlfriend turns up to a show with a new fella. In an attempt to appear he's also moved on, he asks Norah, a complete stranger, to be his girlfriend for five minutes. The pair end up having an unforgettable night roaming around Manhattan. Cera said he had real on-screen chemistry with his co-star Kat Dennings, who plays Norah. He said of the characters: "They have a connection and can talk to each other and seem to be being themselves with each other. There's no pretenses right away." Nick and Norah's Indefinite Playlist opens in the UK on January 30.
