Producer Frank Marshall revealed to ComingSoon.net that since they now have access to the entire library of Robert Ludlum, the late-author’s novel The Parsifal Mosaic may be one of the potential sources of material for the next film:
Question: Would you want to do a straight adaptation from one of the novels?
Frank Marshall: Actually, there is. “The Parsifal Mosaic” is one that we like.
Marshall also said that Matt Damon hasn’t signed on yet, and in fact, he and the writer (George Nolfi) are the only two signed on.
Here’s some of the plot summary of The Parsifal Mosaic via Wikipedia:
Michael Havelock, (an anglicized version of Mikhail Havlíček), is an intelligence agent in the United States. At the beginning of the novel he believes he has just witnessed the execution of his partner and the love of his life, Jenna Karas (anglicized version of Jenna Karasova) along an isolated stretch of the Costa Brava. Jenna had been marked for execution because she had been proved to be a KGB double agent.
