When it comes to sifting through all actors responsible for portraying the most powerful man on the planet, there's no shortage of options. John Travolta did a great Bill Clinton impersonation in Primary Colors and Timothy Bottoms delivered a near-perfect imitation of George W. Bush in both D.C. 9/11: Time of Crisis and That's My Bush! Neither one comes across as particularly flattering, so presidential nominee Barack Obama has chosen a safer bet: At a recent party in Los Angeles, Obama revealed that he prefers Jeff Bridges' conflicted commander-in-chief in The Contender. Granted, he may have said this simply to keep his audience happy -- in this case, Contender director Rod Lurie, one of the attendees who was willing to plop down $28,000 for the event. "'I just plugged your movie," Obama told Lurie, according to a report the director sent to Hollywood Elsewhere's Jeffrey Wells.

Still, when you're under the kind of intense scrutiny that Obama currently endures, Bridges actually seems like a pretty safe choice. Choose Anthony Hopkins in Nixon and it sounds like you're endorsing the bad guy. Choose Kevin Kline in Dave and you come across as disingenuous. Choose Peter Sellers in Dr. Strangelove and somebody will call you incompetent. Bridges, on the other hand, plays a fierce leader bound to his moral convictions. Of course, Obama also expressed sympathy over Lurie's short-lived television show Commander-in-Chief, which featured Geena Davis as the first woman president. Perhaps it's no coincidence that he and Hillary have publicly made amends.

Yesterday's New York Post contained a gossip item in Page Six taken from the book party for James Rosen's The Strong Man: John Mitchell and the Secrets of Watergate in New York, where attendee Tony Danza expressed an interest in playing Richard Nixon aide H.R. Halderman -- maybe in a movie version of Rosen's book. Halderman, who died in 1993, worked for Nixon as White House Chief of Staff until the Watergate scandal landed him eighteen months in prison in 1973. His story, partially recounted in The Strong Man, involved a longstanding relationship with Nixon going back to the 1950s and the tense moments immediately before and after the president's resignation. In between, he was involved in a botched attempt to assassinate Fidel Castro and other tumultuous events dutifully recorded in Halderman's diary, which became available to the public years later.

Many political scandals often revolve around a single corrupt individual, but it's the right hand man whose story can be most revealing. (Roy Cohen's personal drama has way more twists than that of Joseph McCarthy, for example.) There's little doubt that Halderman's experiences would work well on the big screen, but this wouldn't be the first time: IMDb lists no less than five actors who have portrayed Halderman, including James Downing in The Pentagon Papers, as recently as 2003. Would Danza make sense in this role? And will any film have a chance at getting people interested in this story after Frost/Nixon nabs the spotlight later this year?

So far, there are only a few actors officially attached to Oliver Stone's W., the epic biopic about our current commander-in-chief. Josh Brolin was cast as President George W. Bush back in January, then recently Elizabeth Banks was chosen as his wife, First Lady Laura Bush, and last week James Cromwell and Ellen Burstyn were locked into the roles of former President George H.W. Bush and former first lady Barbara Bush, respectively. Unofficial casting bites, though, include a lot of other big name actors. Jeffrey Wright is reportedly in negotiations to play Colin Powell, Tommy Lee Jones is supposedly being sought for Donald Rumsfeld, Robert Duvall has been rumored to be the choice for Vice President Dick Cheney and now both Paul Giamatti and Toby Jones are being named as potentials for the part of Karl Rove (who Giamatti may have already channeled for his character in Shoot 'Em Up).
