What does Clive Owen mean when he says in the movie "Inside Man"?

Question

"And therein, as the Bard would tell us, lies the rub"

Answer 1

Well, it means like "there's the problem" or "there's the hitch" or something like that. It's Shakespeare from Hamlet.
It goes something like, "to sleep perchance to dream, aye but therein lies the rub, for in that sleep of death what dreams may come." Meaning something like, if you're going to die in order to dream, well, that's a problem, because that's a "sleep" that has no dreams.

Answer 2

that was a good movie

***SPOILER ALERT***





I love how you're led to believe throughout the entire movie that he's in jail, and how he says hes in a tiny cell, like jail. At the end I felt like I've been played for a fool...it was neat

Answer 3

I'm guessing something shakespearian...who cares?! He's hot!
