A new Bourne film starring Jeremy Renner is still ''moving forward'', according to series producer Frank Marshall.

Earlier this week, it was reported that Hollywood superstar Matt Damon is currently locked in talks over making another Bourne flick - but Marshall insists plans to make another film with Renner as the focal point are also progressing.

Speaking to the Hollywood Reporter, Marshall explained: ''That movie is moving forward. It's still in development. We're working to get a script as soon as possible.''

Of course, Renner replaced Damon in the most-recent Bourne film, entitled 'The Bourne Legacy'.

And it had been speculated that Damon's eagerness to reprise the role may have caused Renner's film to be put on the back burner.

But according to Marshall, that is not the case and the planned film is unaffected by the speculation.

He said that both movies will continue simultaneously should Damon reach an agreement to star in another Bourne film.

Previously, Marshall revealed he would like to ''see Matt and Jeremy team up'' in the next film in the franchise.

It's been confirmed that the next Bourne movie will be released in July 2016.
