Filming will take place in Victoria, with the Paramount+ series covering the 97 days between Patterson’s infamous beef wellington lunch and her arrest.“There have been quite a few [scripts about the mushroom case] floating around, and that’s to be expected,” said Tamara Simoneau, Paramount Australia’s vice president of content. “When something like this happens, a story that the whole country is obsessed with, then the world became obsessed with it, it’s bound to end up in scripts and in writing rooms. We’re really thrilled with what’s transpired for us and the casting of Melanie, who we think will be excellent.”Mushroom Murders was one of the headline announcements at the combined Ten/Paramount Australia upfronts event on Wednesday, which unveiled a slate heavy on local crime for the streamer, including a six-part adaptation of the 2019 podcast Who the Hell is Hamish? and a true-crime series fronted by Teacher’s Pet reporter Hedley Thomas.In Who the Hell is Hamish?
