Hugh Jackman and Kate Hudson's latest film has upset those close to its real-life subject.

In their new film, "Song Sung Blue," Hudson and Jackman portray the real-life couple Claire "Thunder" and Mike "Lightning" Sardina, who together made up the Neil Diamond tribute band, "Lightning & Thunder."

During a recent interview with the Daily Mail, Mike's children, Michael Sardina Jr. and Angelina, expressed their many issues with the film, including only getting paid $30,000 to consult on the film and Mike Jr.'s assertion that he was "purposely cut out of the film."

"Every interview that those monsters have been on 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," he said of Jackman and Hudson.

While he wasn't included in the film, he participated in the 2008 documentary, "Lighting & Thunder," which told the story of his dad's legacy. The documentary was released two years after his father's death in July 2006 after he suffered a brain bleed following a fall.

Text messages obtained by the Daily Mail between Mike Jr.'s sister, Angelina, and the film's producer, John Fox, confirm the two were paid $30,000 to consult and also showed sympathy on Fox's part, as he told Angelina, "I totally understand, and I'm sorry, know it's not the most ideal situation," regarding their lack of input.

Angelina is included in the movie, portrayed by King Princess, with the Daily Mail reporting she signed a contract in which she authorized the movie to tell a fictionalized version of her story but did not ensure she would be in contact with anyone from the cast, including King Princess.

The two also had issues with the way their father was portrayed. Mike Jr. said if anyone had spoken to them about their father, they would have known that he "would speak in a very, very slow kind of way."

"[My father] would thank God every single show, and then he would go on a very short testimony about his journey through recovery," he recalled. "And if anybody felt like they were alone, or maybe they needed help, or they needed prayer, [he would tell them], "'You come up here after the show, and I will sit here. And I'll talk to you'."

In addition to having no input in the story, Mike Jr. and Angelina say the movie didn't do a good job of showing the tension that existed in their home as they were growing up, with Angelina saying, "The only thing that was true is the love between my dad and Claire."

"I mean, yes, it's a great story," she said. "It's a beautiful story, but that's not how it went down. And I guess that's what's upsetting because it's a lie."

While Mike Jr. and Angelina are upset with the end product, their stepmother Claire, who married Mike Sr. at the Wisconsin State Fair in 1994, and her two kids from a prior marriage — son Dayna and daughter Rachel — have been supportive.

The three happily posed with Jackman and Hudson at the New York City premiere in early December, and Carol and Rachel joined Jackman on stage to sing on separate occasions.

Mike Jr. and Angelina were also invited to the premiere, but, according to Mike Jr., they were told to "keep away from any of the stars and reporters."

"I want the true story out there, and I want it used with truth, with dignity, and I want retribution," Mike Jr. said. "I want retribution from NBCUniversal [and other parties involved], not just for me, for my father, for me, and for my little sister — my father's true descendants — because they screwed us over.

"Everybody thinks it's such a wonderful film, it's so touching," he added. "It's all lies. And it steals all the hard work that my father put in his entire life so that Claire, Rachel and Dayna can soak up a massive paycheck."

Former special counsel Jack Smith undercut claims made by Cassidy Hutchinson, a former White House aide and Jan. 6 Committee witness, as he was testifying in a recent deposition to Congress.

Smith told the House Judiciary Committee this month, according to a transcript published Wednesday, that he evaluated Hutchinson's explosive claims as part of his investigation and prosecution of President Donald Trump related to the 2020 election. Smith said they had deficiencies because Hutchinson did not offer firsthand information.

Asked during the deposition how he would have approached cross-examining Hutchinson, Smith said he would have moved to prohibit a portion of her testimony from being used.

JACK SMITH DENIES POLITICS PLAYED ANY ROLE IN TRUMP PROSECUTIONS AT HOUSE HEARING

"If I were a defense attorney and Ms. Hutchinson were a witness, the first thing I would do was seek to preclude some of her testimony because it was hearsay, and I don’t have the full range of her testimony in front of me right now, but I do remember that that was a decent part of it," Smith said.

Smith was also asked about specific claims Hutchinson had made, including that Trump was aware that some of his supporters would be armed at his rally and that Trump attempted to grab the steering wheel of his driver out of anger.

Hutchinson "was a second or even thirdhand witness," Smith said, adding that other witnesses gave "different perspectives" than her. 

"We interviewed, I think, the people she talked to, and we also interviewed, if my recollection is correct, officers who were there, including the officer who was in the car," Smith said. "And that officer, if my recollection is correct, and I want to make sure I’m right about this, said that President Trump was very angry and wanted to go to the Capitol, but the version of events that he explained was not the same as what Cassidy Hutchinson said she heard from somebody secondhand."

Smith noted that "a number of the things that she gave evidence on were secondhand hearsay, were things that she had heard from other people and, as a result, that testimony may or may not be admissible, and it certainly wouldn’t be as powerful as firsthand testimony."

Hutchinson became a key witness in the Democrat-led Jan. 6 Committee’s investigation into the U.S. Capitol attack, testifying privately several times and publicly. Her testimony dominated headlines, but her claims became a point of scrutiny for Republicans, who found the committee's work lacked credibility because its only Republican members were two vocal anti-Trump lawmakers.

Hutchinson served as a top aide to White House Chief of Staff Mark Meadows in the final months of Trump’s first presidency, giving her an inside look at internal discussions among White House officials in the aftermath of the 2020 election. 

JACK SMITH SUBPOENAED FOR DEPOSITION WITH HOUSE JUDICIARY COMMITTEE

In a highly publicized hearing in June 2022, Hutchinson testified under oath about what she said were warnings inside the White House about the possibility of violence on Jan. 6 and Trump’s alleged awareness that some supporters attending his rally would be armed.

In another claim that was later disputed by other witnesses, Hutchinson also recalled conversations about how Trump attempted to grab the steering wheel from a U.S. Secret Service agent because he wanted to go to the Capitol and not the West Wing.

Hutchinson testified that she was told that the president "said something to the effect of, 'I'm the effing president, take me up to the Capitol now,' to which [the agent] responded, 'Sir, we have to go back to the West Wing.' The president reached up towards the front of the vehicle to grab at the steering wheel."

Hutchinson had not mentioned that particular story in any of her prior interviews with the committee. She later said she withheld it at the direction of her former lawyer, Stafan Passantino.

Smith was asked about Hutchinson as part of a more than eight-hour closed-door deposition this month that centered on his investigations and prosecutions of Trump related to the 2020 election and Trump's alleged retention of classified material.

Smith also defended his investigative practices, including subpoenaing Senate and House lawmakers' phone data. He also defended some of his prosecutorial decisions, including seeking gag orders against Trump and bringing an unusually slimmed-down superseding indictment against Trump after the Supreme Court ruled that Trump had some presidential immunity protections.
