Columbia Pictures is planning to reunite Harold Ramis, Bill Murray, Dan Aykroyd and Ernie Hudson for a sequel of its blockbuster "Ghostbusters," according to Variety.

They will once again make up the most famous ghost-hunting group of scientists.

Variety also informed that Lee Eisenberg and Gene Stupnitsky will be writing the script. Stupnitsky and Eisenberg were nominated for an Emmy for the NBC sitcom "The Office," and are already teamed up with ghost buster Ramis with whom they wrote the comedy "Year One." It is produced by Judd Apatow and directed by Ramis, and scheduled for release in 2009 by Sony.

"Ghostbusters" was Columbia's highest earning film ever, until it was beaten by "Men in Black" and then "Spider-Man."

Despite Columbia’s plans to feature all the busters in the new film, no deals will be made with the original cast until the script is ready. Aykroyd however has been pulling strings for a long time for this sequel to actually take place.

Regarding the film’s director, there is no word on whether Canadian Director Ivan Reitman, who made both the 1984 original and its 1989 sequel, would direct any third movie.

Ivan Reitman, as a producer and director, has created many of American cinema's most successful and best loved feature film comedies and has worked with Hollywood's acting elite. Reitman has produced such hits as the ground-breaking sensation National Lampoon's Animal House (1978), which introduced John Belushi to American filmgoers, and the family features Beethoven (1992) and Beethoven's 2nd (1993).
