20 Things You Never Knew About Star Trek: Insurrection
18. Abandon Hope, All Ye Who Enter Here
Anthony Zerbe plays Admiral Matthew Dougherty in the film, though he was actually considered originally for the role of Adhar Ru'afo. Though he auditioned well, that role was given to F. Murray Abraham.
As part of his audition, Zerbe used his own unique style of acting to secure the part, including going completely off-script! Rather than recite the lines as provided, he instead performed a chunk of Dante's Inferno. Only after he had completed these passages, did he then switch back to the script as it was.
This would prove to be a slightly apt decision, as Admiral Dougherty himself makes many bargains with the Devil during his time in the film. Though it is all done for altruistic reasons, the S'ona Alliance is one that is clearly about as secure as an alliance with the Borg.
