Good choice, Denzel has the action and acting creds for the part.
Is this the film version of the TV show? Never seen the show but casting Denzel is always a plus.
I like Denzel Washington, and he can certainly play that kind of character, but he's so unlike Edward Woodward, I just don't know.
Then again, a casting choice like that probably wasn't made lightly, so I'll be interested in seeing where they go with this.
Couple of years ago, I had seen a piece that said Russell Crowe was up for the part.
Didn't know they were bringing this back in some way. Huh. Anyway, the show has one of the coolest intros ever:
