Since Brittany Murphy became the latest celebrity to land a biopic that will air on Lifetime, 'The Brittany Murphy Story,' her father has not kept quiet about his disgust with the entire project when viewing commercials that are leading up to its Sept. 6th premiere.

Bertolotti has been taking to Twitter to rant about the "cheap" biopic, taking aim at the plot as well as the actress who was cast as his late daughter, Amanda Fuller.

"My daughter #brittanymurphy would be horrified to know who they chose to play her and how cheap it all is," he tweeted on Monday (Sept 1st). "#brittanymurphy would have been MORTIFIED if she knew what a mockery they made of her life and her gorgeous looks and talent. #Unauthorized."

The disgruntled parent also expressed his anger at the television network when speaking with Examiner.com, saying he is "disgusted and outraged that Lifetime decided to produce such a trashy project."

"Frankly, I am amazed at their audacity of calling it "a true story," without conducting any research or consulting with any members of the family," he added. "'The Brittany Murphy Story' is an affront to everything my daughter was in real life. It's hideous, unauthorized and completely untrue."

Bertolotti was mostly distressed when the biopic depicted him as an estranged father, portraying his ex-wife Sharon as Brittany's primary parent. During his lengthy rant, he also took a shot at the 30 year-old actress playing the lead role.

"Lifetime's casting was atrocious," he stated. "Amanda Fuller, the girl playing Brittany, looks absolutely nothing like her. Everyone looks ridiculous in their bad wigs and the dialogue is nauseating."

After being taunted online by Bertolotti, Fuller - best known from ABC's 'Last Man Standing - hit back in an interview with The TV Page, defending the movie.

"It is what it is," she said. "All our hearts were in the right place. I had two days to prepare."

"He has already gone and attacked me on Twitter and I have had to block him and that is fine," she continued. "He can do what he wants. But I just think it is interesting that the minute she is back in the press he is all about, 'I am going to sue' and all that stuff."

"If he really respected his daughter's memory then I don't know if he would be trying to make all this controversy about it," Fuller added. "Let her rest in peace."

The straight-to-television movie will run for two hours, and will be the first lengthy production that attempts to retell the life of Murphy, who died almost five years ago at 32 years-old.
