The US version of Kath & Kim is being revamped to make it more appealing to American audiences, after network executives expressed concerns with the first episode.
The show, starring Selma Blair and Molly Shannon, is believed to be undergoing some emergency reworking.
The move comes after influential US media industry group Horizon Media, which is responsible for analyzing the new shows for the fall TV season, predicted the program would fall flat with US audiences.
The production is rumored to have had a major shake-up in recent days, with a number of key crew - including the director, director of photography, the hair and make-up team and editor - apparently being replaced.
The first episode, which is due to air on NBC on October 9, is understood to be undergoing heavy reworking and may even be reshot.
NBC has invested heavily in the show, giving it prime placement in its Thursday evening comedy line-up. But sources say executives have asked the show be "more highly stylised".
"Think CSI: Comedy. * They want to de-Kath & Kim it a bit," the industry insider said.
Kath & Kim's creators and Australian stars, Gina Riley and Jane Turner, and executive producer Rick McKenna, have been heavily involved in the development of the US version of the show. All three are executive producers of the series.
Currently in America, McKenna could not be contacted to comment on the rumored changes to the show.
*What in the world does this mean? Asking me to "think CSI: Comedy" does nothing, since I'm not sure what the heck that could possibly entail.
