It is a feature designed to mark Facebook's tenth anniversary - and, presumably, to make its 1.23 billion users a little misty-eyed with nostalgia.
The Look Back video selects the biggest moments of your Facebook life and presents them in a cheesy, one-minute show reel.
Pictures, status updates, 'life events' - the most significant snippets of your social networking life have been garnered from everything you've posted since the day you joined Facebook and packaged into a video.
You can even share your Look Back video on your own timeline, should you wish.
However, not everyone has been entirely happy with the content chosen by Facebook's auto-selection algorithms.
Whether it's an unflattering picture, an embarrassingly drunken status update or details from a relationship you'd rather forget, many have been complaining about their videos.
Fear not, this is a glitch Facebook seems keen to rectify.
Techies at the social networking site are working on an editing tool so people can remove and replace content.
A spokesman told TechCrunch: 'We will be launching an edit feature soon that will allow people to change moments in their movies or update the ones they shared. I don't have exact timing at the moment, but this will enable people to remove a post from the movie that was pre-selected and change it to a different one.'
