This is a great thread! First of all, pure shameless plug - I spent a year researching and writing THE REDEMPTION OF PONTIUS PILATE, a novel about Pilate's career, the trial of Jesus, and its aftermath both locally and in Pilate's life.
Also, I should note that Justin Martyr, in his FIRST APOLOGY written to the Emperor Antoninus Pius, after recounting the history of the crucifixion, commented "that these things did happen, you can ascertain for yourself by consulting the Acts of Pontius Pilate."
At one time there was a report filed to Rome about the events of that tumultuous Passover weekend. A shame it's lost to history! (I did write a novel about that, too, actually!!! ;-) )
