Firstly, let me just say, I'm psyched. I've even been waiting patiently in anticipation for the genius that I knew would be this trailer. I know, I'm weird - and proud of it - normal people are boring.
Anyway, that said, I'm sitting here debating with myself (again a total crazy person) on the plausibility of this premise. Man is hired to kill people who are sent back in time to him from the future (that I'm cool with). All is running smoothly until he's assigned to kill his future self... watch this part of the trailer. I don't know if I'd be able to recognize my old-self in a matter of seconds like he does above. Not to mention how much Joseph Gordon-Levitt and Bruce Willis look nothing alike. I guess they're trying to suspend our disbelief by giving Gordon-Levitt green contact lenses.
Oh well, otherwise I'm 100% on board. Thoughts?
