Google Video Player has "Murder in Rome," a 45 minute dramatization of the trial of Sextus Roscius, which made Cicero's reputation in his early career. The advocate himself is played by a handsome and utterly captivating Paul Rhys (they know how to grow men in Wales), and Sextus is played by Mark McGann. I've been trying to find this for a year or so and this just made my night, along with the next exiting bit of news!
The second part to Robert Harris' Cicero trilogy has a title and release date! Titan will come out sometime in October of this year, and based on the timeline (Cicero was just elected consul at the end of the first book, Imperium), it should hit the Catalinian conspiracy and possibly his exile. If you haven't read the first book, definitely give it a try!
