About Time sees Tim (Domhnall Gleeson) discovers that he's the latest in the genetic line of male time travellers (the gift doesn't extend to the family's ladies). After taking some advice from his pa (Bill Nighy), Tim uses his new-found ability to land himself a girlfriend, quickly falling in love with Mary (Rachel McAdams).
What follows is less a Groundhog Day redo, and more a gentle examination of second chances and day-seizing. The fact that it's written and directed by Richard Curtis (Love Actually, The Boat That Rocked) should give you an early indication of whether you'll love it or hate it, find it cosy or cloying.
As the trailer revealed, the film will show the ups and downs of time travel, even if the logic ain't exactly Primer-rigorous.
About Time opens in the UK on 4 September 2013, before hitting the US on 8 November 2013.
