“Bourne 5” is adding new cast members, and Julia Stiles is set to return, according to reports. Other reports suggest that the role of the villain may be played by Viggo Mortensen, who is well-known for his role as Aragorn in the “Lord of the Rings” movies.

According to a report by Latino-Review, Stiles will reprise her role as spy handler Nicky Parsons, who used to handle logistics. Matt Damon will reprise his role as Jason Bourne, a spy suffering from amnesia. The movie is reportedly being directed by Paul Greengrass.

Stiles last played the role in 2007's “The Bourne Ultimatum.” She has since been involved with “Silver Linings Playbook” and “Closed Circuit.” She has also been a cast member in TV series such as “The Mindy Project,” “Dexter” and “Blue.” Neither Damon nor Stiles were involved in 2012's “The Bourne Legacy,” which starred Jeremy Renner and was directed by Tony Gilroy.

According to the report, Alicia Vikander is said to be in negotiations with producers to join the “Bourne 5” cast. The producers have yet to reveal the plot or the full title of the forthcoming movie.

Vikander appeared in the sci-fi drama “Ex Machina.” She was also a cast member in “Seventh Son,” “Testament of Youth” and “A Royal Affair.” The actress will be seen next onscreen in “The Man from U.N.C.L.E,” which stars Henry Cavill and was directed by Guy Ritchie.

According to a report by Joblo, Mortensen has been offered the role of the new villain in Greengrass’ movie. The report states that the actor has yet to sign the deal, and his appearance in the movie has still not been confirmed. The report does note that Mortensen had to turn down a role in “The Hateful Eight” because of conflicts in the filming schedule and also adds that the actor is “pretty picky” about the roles he plays.

Since playing Aragorn, the actor has been a part of many movie projects, including “Hidalgo,” “Eastern Promises,” “Far from Men,” “The Road” and “Appaloosa.” He will next be seen in the 2015 movie “Captain Fantastic.” “Bourne 5” is slated to be released on July 29, 2016 in the U.S.
