This is old news. It all came about because Harold Ramis gets asked about it all the time. He revealed the idea he had for what Hell would be like and said that they would get a group of yonger, funny, actors "Like Ben Stiller".
At the end of the day, IMDB works through user submissions (Which is why so much false news is put up there). Some joker has just decided to put this film down as 'In Production'.
