"Jekyll" (BBC)

For those interested, you should check out the BBC series, "Jekyll." It is a wonderfully inventive take on the Jekyll/Hyde complex in our modern era.

Plus, the series includes one of the best lines ever...

As Jekyll turns into Hyde, Hyde comes across a young couple arguing in an alley. In sum, Hyde stomps on the male, which causes the female to start crying and screaming. And then Hyde circles around to the female, talking to her about lions and predation. And then the female tries to run away... which causes Hyde to say the following:

"Oh no no no. Don't run. Do you know what runs? ... prey runs."
