The 59-year-old Irish actor will star alongside Jessica Alba and Kristin Scott Thomas in Tom Vaughan's film, reported Daily Star.
Brosnan's character, a Cambridge University professor, is forced to re-evaluate his life when a girlfriend (Alba) falls pregnant with his baby.
Scott Thomas will play the 'Fantastic Four' star's sister. The film will be pitched to buyers at the Cannes Film Festival, alongside Brosnan's 'The Moon And The Sun', in which he'll play French king Louis XIV.
