Rafe Spall is joining the cast of romantic comedy The F Word.
The Prometheus star will appear alongside Harry Potter's Daniel Radcliffe and Revolutionary Road actress Zoe Kazan in Canadian director Michael Dowse's film, Variety reports.
Daniel and Zoe will play two young people who meet at a party and find themselves attracted to one another, but try to stay just friends as she has a long-term boyfriend, played by Rafe.
Rafe is used to playing a cuckold after he starred as Anne Hathaway's hapless boyfriend Ian in One Day, about a girl who was in love with her male best friend.
The F Word is due to start filming this month in Toronto and Dublin.
