One of the many things Illinois Governor Rod Blagojevich did this week — instead of resigning from his position, as many people desired — was sign into law an increase on tax credits for films produced in his state. So, it should be only appropriate, and somewhat bittersweet, for the inevitable movie about his life and corruption hearings to be shot there.

Now that we’ve got a location for the film, it’s time to cast the players in Blogojevich’s scandalous tale. The Washington Post has already published a list of possible actors to portray the lead (John Travolta, Sean Astin, Gary Cole, Stephen Baldwin, Tom Cruise, Ray Liotta, Charlie Sheen, Mike Myers and Steve Carrell), but more difficult than casting Blogojevich (see our pick below) is determining what other significant figures should be prominently featured.

A straight biopic calls for way too many characters, so we’ve narrowed the film down to focus on just Blagojevich’s arrest and subsequent (forthcoming) trial. As always, if there’s another character to be included or another thespian suited to a role we’ve cast, chime in with a comment. Also, due to the fact that we’ve previously done posts about Barack Obama casting, let’s just assume that he’ll only be portrayed by a voice on the phone, a la Al Gore in Recount.

Sam Rockwell as Governor Rod Blogojevich

The perfect look-a-like casting choice would be former Attorney General Janet Reno, but Sam Rockwell (Frost/Nixon) is also a pretty close match. The actor has already played a lot of sleazy characters, including the lead role in Choke, for which he was recently named one of the “most offensive male characters” of 2008 by the Women Film Critics Circle. Rockwell also has experience portraying a conceited and delusional celebrity in George Clooney’s Confessions of a Dangerous Mind. If that actor-director pair could link up again for this movie, Rockwell could certainly be looking at his first well-deserved Oscar nomination.

Mary Lynn Rajskub as Patti Blogojevich

Rockwell is a tad young for the role of Blogojevich, so it’s fair that we also aim younger in casting the actress to play Illinois’ First Lady. Few women are more perfect for the part than Mary Lynn Rajskub (TV’s 24), who is about 8 years Blogojevich’s junior, anyway. Talented for playing cranky and/or two-faced women (mainly we’re thinking of her character in Punch-Drunk Love), she would be excellent as the allegedly foul-mouthed wife of the Governor.

Mario Van Peebles as U.S. Representative Jesse Jackson, Jr.

Fittingly the son of an important African American leader (though being an icon of black cinema is admittedly not quite the same as being an icon of the civil rights movement), Mario Van Peebles (Ali) is conversely too old to play this part, especially since Jackson looks a lot younger than he is. But he’s a great, underrated actor (too good for All My Children, that’s for sure) and he could easily pull off a portrayal of the congressman, who was one of the contenders for Barack Obama’s now-vacant Senate seat, and who has apparently been a longtime informant to feds regarding Blagojevich’s shady dealings.

Martin Donovan as U.S. Attorney Patrick Fitzgerald

One idea for the part of the federal prosecutor in this case is Richard “John Boy” Thomas. He does look a little more like Fitzgerald, but Martin Donovan (Saved!)  got the Irish-American thing going for him, and it would be more interesting to see if he can do the Brooklyn accent. Plus, Donovan often works with Mary-Louise Parker, who would be perfect for the part of Illinois Attorney General Lisa Madigan if she were an included character in the film.

Brian Cox (or Albert Finney) as Defense Attorney Ed Genson

An immediate idea following a Google image search was to jokingly cast actor Kevin Scannell, who played wheelchair-bound lawyer “Gar Girard” in The Player. But as it turns out, contrary to most photos available on the web, Genson no longer has such a handicap. So, a more appropriate suggestion for the famously tough lawyer (often called “the bulldog of the court room”), who formerly won R. Kelly’s child-pornography trial and who will now defend Blagojevich, is The Bourne Identy’s Brian Cox (not ever called “the bulldog of cinema,” though he should be). Or, in the event that you too think he’s easily interchangeable with Cox, Albert Finney (The Bourne Ultimatum) would also be suitable. Whichever of the two is cast, he’ll have to either get Genson’s accent down or have his dialogue overdubbed by William Hurt.

James Woods as Lt. Governor Pat Quinn

He may not really look like Quinn, but James Woods (Ghosts of Mississippi) is terrific at changing his appearance for Oscar-worthy supporting roles. This might not be a big enough part for an actor of his stature, but he’d be great at aping the wide-eyed expressions Quinn does when speaking publicly.

Stanley Tucci as Antoin “Tony” Rezko

It’s not certain yet if convicted fundraiser Tony Rezko will be involved in Blagojevich’s trial, though his testimonial would serve the prosecution well. If he is a major player, then Stanley Tucci (The Devil Wears Prada), with a puffy makeup job and fake mustache, should fill the role. Although Tucci is not Syrian like Rezko, he did once play a Middle Eastern assassin in The Pelican Brief.

William Petersen as John Harris

As Blagojevich’s former Chief of Staff, who resigned from his position after his joint arrest with the governor last week, William Petersen (TV’s CSI) would callback to his similar role as a political scandal figure in The Contender.

“The Football” as Itself

One of the harshest punishments for Blagojevich would be for the feds to deny the Governor his beloved hairbrush, which is nicknamed “The Football” (after a term used for the president’s possession of bomb codes). Then, producers of the Blagojevich film should purchase the item for a cameo appearance. Because, as the Governor would declare, there’s no substitute for it.
