Working Title has released the first trailer for director Richard Curtis’ (Love Actually) new film About Time.  The pic puts a time travel spin on the classic romantic comedy conceit, as Domnhall Gleeson (Bill Weasley from Harry Potter) plays a man who has inherited the ability to travel through time from his father (Bill Nighy).  Naturally, Gleeson’s character uses his time travel prowess to woo the girl of his dreams (Rachel McAdams), but as with all time travel stories, the powers come with grave consequences.  Curtis has a knack for making familiar stories interesting and endearing, and About Time looks to be no different.  I like the earnestness with which the film is approached, and Gleeson seems poised to break out in a big way.

Hit the jump to watch the debut UK trailer.  The film also stars Tom Hollander, Margot Robbie, Lydia Wilson, and Vanessa Kirby.  About Time opens on September 6th in the UK and November 1st in the US. [Update: We've added the just-released US trailer (which gives away too much), poster, and images.]

Here's the synopsis for About Time:

At the age of 21, Tim Lake (Domhnall Gleeson) discovers he can travel in time…

The night after another unsatisfactory New Year party, Tim’s father (Bill Nighy) tells his son that the men in his family have always had the ability to travel through time. Tim can’t change history, but he can change what happens and has happened in his own life—so he decides to make his world a better place…by getting a girlfriend. Sadly, that turns out not to be as easy as you might think.

Moving from the Cornwall coast to London to train as a lawyer, Tim finally meets the beautiful but insecure Mary (Rachel McAdams). They fall in love, then an unfortunate time-travel incident means he’s never met her at all. So they meet for the first time again—and again—but finally, after a lot of cunning time-traveling, he wins her heart.

Tim then uses his power to create the perfect romantic proposal, to save his wedding from the worst best-man speeches, to save his best friend from professional disaster and to get his pregnant wife to the hospital in time for the birth of their daughter, despite a nasty traffic jam outside Abbey Road.

But as his unusual life progresses, Tim finds out that his unique gift can’t save him from the sorrows and ups and downs that affect all families, everywhere. There are great limits to what time travel can achieve, and it can be dangerous too. About Time is a comedy about love and time travel, which discovers that, in the end, making the most of life may not need time travel at all.
