It's a quite old movie (about 2000th). I think it was intense plot movie.
It's possible that the main actor was Ben Affleck, but I'm not sure.
He had to do some kind of mission with a women. After a time she changed her hair colour (to red or gingery), because she had to disguise herself. They made a team to get some kind of money. Man was thinking that this women swindled him, but it was a trick to succeed at this mission.
I remember that there was some kind of gangster who wanted to kill the main character, if he will not get the money,

OH and most important! There was a moment at this movie, when electric clock showed up. [it was 11:11] they (women and man) were standing outside, women were smoking and it was dark and then she looked at the clock and sad: "11:11 make a wish!!!"

So that's about it.
I'm trying to find this movie for such a long time. I would really appreciate if you could help me! :)

Nothing really comes to mind and I have seen most of the movies Ben Afflevk has been in but I will give you a link that has all his movies and maybe that will bring you closer to finding your answer.

Ben Affleck - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Ben_Affleck)

Well. I have searched also in his movies, but there isn't this one.
I guess that means that this main actor was not Ben Affleck :D

OK, sorry I could not help further. I will put some thought into it and hopefully someone will come along and help you with it.

Hope so. ;]
