Curtis and Grant have collaborated on several films, including Bridget Jones's Diary, Notting Hill and Four Weddings and a Funeral.

McCutcheon hopes to make the transition from small to big screen

The writer is credited with giving the British film industry a huge boost through his string of box office hits.

Curtis had a successful television career before he made his name in film, creating hit shows such as Blackadder and The Vicar of Dibley.

The film will be produced by Tim Bevan and Eric Fellner from Working Title Films.

The Toronto Film Festival will also premi�re Philip Saville's The Gospel of John, a three-hour contemporary version of the disciple's life.

The film is narrated by Christopher Plummer and will star Henry Ian Cusick as Jesus.

Philip Saville directed the 1997 comedy drama Metroland.

The Toronto film festival began as a low-key event for local film buffs when it began nearly 30 years ago.

Since then, it has grown into one of the world's top movie showcases.
