By 2004, movement on a sequel was revisited by the studio, though Bill Murray expressed his disinterest in the project stating that he dislikes sequels. The following year, Ramis confirmed plans to introduce Ben Stiller into the principal cast. By 2009, however development of the project had stalled. Both Ramis and Aykroyd subsequently confirmed that the script calls for a new group of younger Ghostbusters, with the latter stating that the cast would feature a gender diversity and include new technology used by the titular team. By January 2010, Reitman confirmed that he would be directing the film. In March, Murray discussed development of the film, and his intentions to reprise his role. A release was scheduled for Christmas 2012. In the October issue of Vanity Fair, Aykroyd commented on the screenplay written by Gene Stupnitsky and Lee Eisenberg, stating that he was particularly impressed with how Murray's character had been written, and the implementation of the new team with the original team, while he and Ramis would work on a second draft of the script.
