Robert Wisdom – Probably best known for his role as Maj. Howard "Bunny" Colvin in HBO's The Wire, Wisdom has also recently been seen in The Dark Knight Rises and taking a more villainous turn in USA's Burn Notice. No matter the role, Wisdom always presents a powerful presence, but does so with a disturbingly calm and cool demeanor (that is the kind of personality of a criminal who knows he's untouchable). At home on the small screen or in summer blockbusters, Wisdom is easily a top choice for Wilson Fisk.
Dean Norris – One doesn't simply give an outstanding performance on Breaking Bad and not expect people to want him doing the same on other programs. Besides, thanks to his Breaking Bad hairstylist, Dean Norris already has the look of Wilson Fisk down. Add that to Norris' keen ability to convey a quiet sense of escalating rage and accurately portray a person comfortable in a position of what he believes to be unquestionable authority, and he could easily bring some much-needed intensity to the role.
Michael Rooker – What if Wilson Fisk were just a little unhinged, just a little more prone to letting the dangerous beast out of its cage, even though a certain situation calls for some decorum? If that's the case, then who better to play Kingpin than the guy who has been menacing other characters in projects like Henry: Portrait of a Serial Killer, Mallrats and, of course, The Walking Dead? Rooker would be an interesting (but undoubtedly compelling) choice that would have audiences convinced of Fisk's villainy by mention of the actor's name alone.
