Hugh Jackman and Kate Hudson's new movie, Song Sung Blue, seemingly doesn't have the approval from Claire and Mike Sardina's entire family. "Everybody thinks it's such a wonderful film [and] it's so touching. It's all lies," the couple's son, Michael Sardina Jr., told the Daily Mail on Monday, December 29. "It steals all the hard work that my father put in his entire life." Jackman, 57, and Hudson, 46, portray Mike, who died in 2006, and Claire, respectively, in Song Sung Blue, a film inspired by the couple's career fronting a Neil Diamond cover band. According to Michael Jr., 41, his father would likely be "rolling in his grave right now" over the screen adaptation. (In addition to Michael Jr., Mike and Claire were parents of daughter Angelina Sardina. Claire also had two children from a previous relationship.) Hugh Jackman Trolls Ryan Reynolds With 2025 Gotham Musical Tribute Award "Every interview that those monsters have been on national television don't even mention my existence at all, even though I was the most prevalent force in my father's life, even when I wasn't in Wisconsin because I'm his only son," Michael Jr. claimed to the outlet. "They didn't even try to contact me. ... They didn't try to get more information." He continued, "I want the true story out there and I want it used with truth [and] with dignity." Neither Jackman nor Hudson have publicly addressed Michael Jr.'s criticism, which has been echoed by Angelina. "The only thing that was true is the love between my dad and Claire," Angelina told the Daily Mail. "It's a beautiful story, but that's not how it went down. I guess that's what's upsetting because it's a lie." Michael Jr. and Angelina's mother, Claire, however, has been completely supportive of the picture.

"It brings back a lot of memories: good, bad, indifferent, love story, music [and] Milwaukee." Director Craig Brewer, for his part, has also been vocal about honoring the Sardinas' legacy in the film. "The great thing about making movies about musicians or artists is that they understand that it's those darker elements, or those moments where there's pain, that are truly the ingredients of great music and great art," Brewer, 54, told Loud and Clear Reviews in an interview published earlier this week. "[The family] supplied me with a lot of other details and stories that really informed me on the script I was writing, but also just on the day ... to tackle certain scenes and deal with the emotions." Kate Hudson Shares How Hugh Jackman Helped Keep Her Silk Dress Wrinkle-Free Brewer stressed that he felt "incredibly indebted" to Mike and Claire's family for openly sharing their story with his crew. "I try to remind people this, many people that come see the film are like, 'Is this a Neil Diamond biopic?' And I go, 'Well, you're half right. It's a biopic. It's just not about Neil Diamond,'" he said. "I think famous people kind of understand, 'Of course, you'd make a movie about my life.' These are two people in the middle of Milwaukee that I don't think more than about 100 people knew about at the time." Song Sung Blue is in theaters now.
