Kate Hudson has addressed the criticism from the son of the real-life couple she and Hugh Jackman portrayed in Song Sung Blue. "Honestly, I don't even know - out of respect for our filmmakers, I'm not the right person to speak to it," the actress, 46, said in an interview with The Hollywood Reporter published on Thursday, January 8. Hudson played Claire Sardina, while Jackman portrayed her husband, Mike Sardina, in the musical film. Claire and Mike performed in the Neil Diamond tribute band, Lightning & Thunder. Song Sung Blue, which is based on a 2008 documentary about Claire and Mike's lives, tells the pair's story as a couple and group as they navigate their ups and downs in the Wisconsin music scene. Mike and Claire's son, Mike Jr., publicly slammed the biopic, claiming it was not a truthful interpretation of his dad's life. (Mike died in 2006 at age 55.) 'Song Sung Blue' Musician's Son Slams Hugh Jackman and Kate Hudson Biopic "Everybody thinks it's such a wonderful film [and] it's so touching. It's all lies," Mike Jr., 41, told the Daily Mail in December 2025. "It steals all the hard work that my father put in his entire life." Mike Jr. claimed he was not consulted about the film and says he does not have an analogous character in the film, unlike his siblings. (In addition to Mike Jr., Claire and Mike shared daughter Angelina. Claire is also the mother of two children from a previous relationship.) "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," Mike Jr. claimed to the outlet. "They didn't even try to contact me. ... They didn't try to get more information." THR reported on Thursday that Mike Jr. was paid as a consultant for Song Sung Blue. Hudson, for her part, told the outlet she spoke with Claire, 64, when making the film. "I'm so happy that I got to know Claire, who's such a wonderful woman," she said. "And she's so happy with the movie." Claire has publicly supported Song Sung Blue in interviews and attended the film's New York City premiere. "It's been surreal," Claire told local Wisconsin outlet WISN last month about the movie's success at the box office. "It brings back a lot of memories: good, bad, indifferent, love story, music [and] Milwaukee." Goldie Hawn and Kurt Russell Sparkle During Rare Family Appearance in NYC Jackman has not addressed Mike Jr.'s claims. Song Sung Blue director Craig Brewer has said that his intention for the film was to honor Mike and Claire's legacy. "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 December 2025. "[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."
