Justin Timberlake and Amanda Seyfried attended a San Diego, Calif. press conference Thursday for their film In Time. The press conference was held at the Hilton Bayfront Hotel during Comic-Con 2011.

Timberlake and Seyfried presented an extended trailer and were received a fanatical response, said THR.

In Time is set in future where people are genetically programmed to live to the age of 25 but can live longer if they buy or steal time credits and also stars Alex Pettyfer, Matt Bomer, and Cillian Murphy.

Justin Timberlake plays a rebel from the ghetto who has been wrongly accused of killing a wealthy man in order to steal time. Timberlake then runs off with his hostage Amanda Seyfried from law enforcement officer The Timekeeper. Time is used as a currency in the film.

Justin Timberlake said of the film, The idea of how could we achieve being young forever... I just fell in love with the man that he was. An ordinary man being put in fantastical situations. He wakes up with 24 hours on his body clock, so he only has a day to live. I liked the idea of what would you do, how would you live; the idea of having to beg and steal to stay alive.

As a director Andrew has the ability to create a thrill ride in the midst of all these ideas. I haven't done a film like this, so I was excited to jump into those running shoes. I run a lot. While it is thrilling, I feel like it is performance driven, he added.
