Jag kollade på Wikipedia också och det verkar ha varit en filmversion på gång men det verkar dött nu.
In the early 2000s, actor Morgan Freeman expressed his desire to produce a film based on Rendezvous with Rama. After a drawn-out development process — which Freeman attributed to difficulties in procuring funding — it appeared in 2003 this would indeed be happening. IMDb at one point upgraded the status of the project to "announced" with an estimated release date in 2009. The film was to be produced by Freeman's production company, Revelations Entertainment. David Fincher, touted on Revelations' Rama web page as far back as 2001, stated in a late 2007 interview (where he also credited the novel as an influence on the films Alien and Star Trek: The Motion Picture) that he is still attached to helm. Revelations and IMDb indicated that Stel Pavlou had written the adaptation.
In late 2008, David Fincher stated the movie is unlikely to be made. "It looks like it's not going to happen. There's no script and as you know, Morgan Freeman's not in the best of health right now. We've been trying to do it but it's probably not going to happen." The IMDb page for the project has been removed.
