It was heartbreaking to hear the news that writer and actor Harold Ramis died over the weekend after his four-year battle with a rare autoimmune disease at age 69.  From 'Stripes' and 'Caddyshack' to 'Ghostbusters' and 'Groundhog Day,' Ramis definately left his mark on the movie industry.  He played many roles both behind and in front of the camera, but in my opinion his most memorable role was that of Dr. Egon Spengler in the 'Ghostbusters' franchise.

A few years back, Ramis confirmed that 'Ghostbusters 3' was in the works.  He was set to make a cameo appearance as Egon, along with Dan Akroyd's Ray Stantz character, and Bill Murray's Peter Venkman.  Despite his tragic passing, Ivan Reitman, director of 'Ghostbusters' and 'Ghostbusters II,' said early this week that production on 'Ghostbusters III' will continue.  The script will need to be revised to remove the Egon Spengler character, but Reitman says that his cameo was so brief that it won't throw off the storyline too much. However, Ernie Hudson thinks differently.

Hudson, who was hired by Ramis to play Winston Zeddmore in 'Ghostbusters' at the beginning of his acting career, says that Harold Ramis was the glue that brought it all together.  Without Ramis, there would be no 'Ghostbusters.'  And although Dan Akroyd is producing the new film that he and Ramis co-wrote along with Etan Cohen, Lee Eisenberg  and Gene Stupnitsky, Hudson is convinced that without Ramis the third installment of 'Ghostbusters' will have to be scrapped.

So what do you think?  Should production of 'Ghostbusters III' move on without the man who brought it all together in the first place?  Leave your thoughts in the comments section. But first, check out an interview with Harold about 'Ghostbusters III,' and then one of the funniest lines from 'Ghostbusters II."
