Representatives for the Gucci family have slammed Ridley Scott's new movie about the fashion house's founders and heirs, insisting it's a very "painful" project to watch.

House of Gucci, starring Adam Driver and Lady Gaga, focuses on the relationship between Maurizio Gucci and Patrizia Reggiani, who hired a hitman to kill the fashion empire heir – and the family isn't happy.

"The production of the film did not bother to consult the heirs before describing Aldo Gucci – president of the company for 30 years – and the members of the Gucci family as thugs, ignorant and insensitive to the world around them…," a statement reads.

"This is extremely painful from a human point of view and an insult to the legacy on which the brand is built today."

The family members are also upset with Gaga's portrayal of real-life character, Reggiani, who was convicted in 1998 as "a victim trying to survive in a male and male chauvinist corporate culture".

"This couldn't be further from the truth," the statement continues. "There were several women who held top positions.

"Gucci is a family that lives honoring the work of its ancestors, whose memory does not deserve to be disturbed to stage a spectacle that is untrue and which does not do justice to its protagonists."

And it appears there could be some legal action coming – the statement concludes with: "The members of the Gucci family reserve the right to take action to protect the name, image and dignity of themselves and their loved ones."

House of Gucci opened in cinemas on Friday.
