When Kristen Wiig signed on to the project, she pushed for Bill Murray to play opposite of her & even though Murray was interested in the project, he procrastinated in reading the script even forgetting about it at one point. Wiig would reach out to Murray reminding him about it even pushing him to read it. But before Murray ever got to read the script, the film's producers persuaded an interested Jack Nicholson to sign on instead. Coincidentally, Nicholson replaced Murray in How Do You Know (2010).
Announced only a month after the original film was released & received an Oscar nomination. It's speedy development was due to Kristen Wiig signing on & Jack Nicholson's interest in possibly coming on to do the project.
When it was first announced it was that Nicholson had bought the rights to remake the film and that he intended to play the father as a nice comeback role. Shortly after Wiig was announced as playing the daughter, the next issue was that Nicholson did not feel up to it. Bill Murray came into the picture at that point after working with Wiig. It seems to differ from the accounts now posted. Nicholson's condition is unknown.
