Back in January 2015, we reported that Oscar-winning actress Reese Witherspoon had signed on to join Matt Damon in director Alexander Payne's Downsizing, which was ironically the second time she had boarded the project. The movie was originally set up back in 2009, but it never moved forward. Today we have a report from Deadline that Reese Witherspoon has dropped out once again due to scheduling conflicts, with Kristen Wiig set to take her place.

The story centers on Matt Damon's character, an ordinary man from Omaha who joins a growing group of people undergoing a process to get shrunk to a fraction of their own size. He then moves to one of the several communities for "small people" that are beginning to sprout up all over the world. No details were given for Kristen Wiig's role, but when Reese Witherspoon landed the role in 2009, she was believed to play a woman who meets this shrinking man.

The supporting cast includes Christoph Waltz and Hong Chau. Actors such as Jason Sudeikis, Alec Baldwin and Neil Patrick Harris were previously attached to this comedy, but they weren't mentioned in this new report, so they may not be involved at this time. It isn't known how many other roles have yet to be cast.

Alexander Payne is directing from a script he co-wrote with Jim Taylor. Both Alexander Payne and Jim Taylor have written a number of scripts together, including Citizen Ruth, Election, About Schmidt and Sideways. Alexander Payne will produce alongside Mark Johnson, with production scheduled to begin this spring.

Kristen Wiig will next be seen in the highly-anticipated Ghostbusters, which hits theaters on July 15. She is also part of the voice cast of the animated comedy Sausage Party, hitting theaters August 12, and her live-action comedy Masterminds debuts on September 30.
