Aisling Bea, writer and star of Channel 4’s upcoming sitcom This Way Up, talks about how the pin-sharp and poignant six-part series explores the social, mental and personal obstacles that people face in their own pursuit of happiness. Bea plays Aine, a woman trying to pull her life back together after a ‘teeny little nervous breakdown’, as her fretful sister Shona (Catastrophe’s Sharon Horgan) worries not only about her sibling, but also about her own life choices.
