As the screen-writer for the first three Bourne films, 'The Bourne Identity, 'Supremacy' and 'Ultimatum' director and wtriter Tony Gilroy provides a much needed link to the previous trilogy for fourth film 'Legacy', especially after director Paul Greengrass and star Matt Damon left.
Yet far from being desperate to continue stringing out a successful franchise he admitted to CNN that initially he was reluctant to continue making films about Robert Ludlum's novels.
He said: "It wasn't something I anticipated".
According to the news network, he had an attitude similar to that of fans who saw no need for a fourth movie, adding: "That's where I started, that's how I came in with that first conversation."
Yet even when ideas started to come together he still wasn't sure about the movie, stating: "I came in and thought, hire me for two weeks and I'll play with that idea and we'll figure out who else at the end of it. And it got better than I thought, quickly, and even still it wasn't something that I was going to write, much less direct."
However eventually he came round to the idea, stating: "I realized what a really sort of exciting piece of meat that was to throw on the grill there, and that's when I got more excited and then ... some time after that, I didn't want to let it go. I got into it, and when we made the deal to write the script, why don't we make a directing deal at the same time."
The new movie will feature Jeremy Renner ('The Avengers') as agent Aaron Cross, a character who shows that the initial conspiracy that trapped Bourne is far greater than previously believed.
