Because their previous roles make it easier to imagine them in the role of a hard-ass slave in a Tarantino flick?
.....................basically lol but i thought Jamie did great in Collateral & Ray. So again, i like the look of it and im sure with Tarantino at the helm, i will eat my words and probably praise Jamie for being outstanding in this lol
I can just picture Leo fucking someone up with that hammer, lol.
I have a feeling he will be channeling a lot of Daniel Day-Lewis' Bill The Butcher. Which wouldn't be a bad thing because it's about time DiCaprio looks beyond his raw acting skills and realizes that you also need to have fun with a role to make it work.
