So I'm being forced to watch The Good Wife last Sunday, and I see that Colin Sweeney, a semi-recurring character Alicia once defended for murdering his wife, was apparently involved in testifying for Alicia's firm for one reason or other (give me a break, the entire hour was me wrestling the remote from my wife and trying to click over to Game 4 of the World Series).

Anyway, the character of Sweeney is played by Dylan Baker. Baker is one of those many actors you've seen in dozens of things and probably never knew his name (that, or you mistakenly called him "William H. Macy). He's played Dr. Curt Connors in the second and third Spider-Man movies, Robert McNamara in Thirteen Days and has probably been on every iteration of Law & Order or C.S.I at one time or another.

But Baker is forever ruined for me because of one of his earlier roles. The character of Sweeney is fairly unsympathetic, it's true, but he could be Santa Claus crossed with Buddha and it wouldn't matter. Because Baker is one of those actors who was so effective as a villain in a former role, I can never see him as anything else. It's such a pervasive phenomenon I've dubbed it "The Pollute of Happiness" (for the movie that started it all), though Baker is far from the only actor involved.

I think anyone who's ever seen any of his movies would agree Todd Solondz has some issues. Having said that, I admire anybody capable of writing a character as chillingly repugnant as Maplewood. And while I couldn't embed the scene that really brings Bill together, here's something a bit...milder.

Admittedly, until recently Kelly rarely played anything but crazy-eyed psychopaths ("I saw Enter the Dragon 87 times!"). The menacing, deranged and ultimately wheedling Luther will always be the best, though.
