In time (2011)

The scene is set in the vast future where humans stop aging at 25 and then die after a year if they dont have time. Time is the currency in the future, the rich say young and immortal forever.The poor perish.And when  Will Salas (Justin Timberlake) is given 100 years by a man because he is tired of his life, everyone goes after him. And this is the tale of how he and his runaway associate Sylvia (Amanda Seyfried); who's a rich business man's daughter; run from the Time keeper Raymond Leon(Cillian Murphy) and practically anyone who stands up against them to stand up against the system.  Not one of the best movies, but definitely worth a watch. The concept is very unique and creative.

Prince of Persia-Sands of time (2010)

Being able to reverse time is a pretty awesome power to have, and in this movie the Young Prince Dastan (Jake Gyllenhaal) exactly has that. But as usual there is a evil out there ready to use the time reversing dagger( yes this gets cooler) for its advantage. Dastan's uncle Nizam (Played by Ben Kingsley) has plans to use the dagger to his own advantage to change the past and transform history to his favor. Gemma Arterton has given full justice to the role of  Fugitive princess Tamina. The prince and the princess take you on and unusual journey full of action, adventure and fantasy! A must watch even for the people who love the game of the same movie.
