Richard Lumsden! I spent most of that episode of Love Soup wondering what I'd seen him in recently, and then remembered that it was 'Sugar Rush' on C4 - he played the husband in that. He was also in 'Is It Legal' on the BBC, and has been in 'The Avengers' and 'Sense and Sensibility' on the big screen. Think he's also got his own production company as well as acting.
