his main character, Mitch Rapp, is loosely portrayed in the Bourne trilogy movie series and Jack Bauer on the TV show 24
I don't think this means what you think it does, unless you are accusing Robert Ludlum of somehow plagiarising a set of books decades in advance. I can see how Jack Bauer's character could have been influenced since the books started coming out a year before 24 series one, but I don't think the character portrayed in the Bourne series is supposed to be anyone but Jason Bourne.
Actually, looking at the precis of the first Rapp book it certainly reminds me of the plot of 24 season 7.
