"To Kevin Spacey, I want to say this: Shame on you for what you did to my son", Unruh said, flanked by her daughter and lawyer Mitchell Garabedian, who has represented hundreds of clergy sexual abuse victims.
Ridley Scott's decision to remove Spacey from the movie has gone down well with film fans on Twitter...
Based on a true story, All the Money in the World details the harrowing 1973 kidnapping of J. Paul Getty's 16-year-old grandson, J. Paul Getty III (Charlie Plummer, no relation), and Getty's refusal to comply with the kidnappers' demands.
According to Deadline, the decision to replace Spacey and reshoot all of his scenes was "unanimous" among the film's cast and crew.
Despite the age difference between the two actors - at 87, Plummer is nearly 30 years Spacey's senior - the recasting will come as a welcome development for director Ridley Scott.
The film was slotted to be shown at AFI Fest in Los Angeles but was pulled Tuesday because of the accusations against Spacey, which continues to mount.
The 58-year-old actor recently faced allegations of sexual assault from Heather Unrah, who in a press conference claimed Spacey grabbed her 18-year-old son's genitals inside a bar on Nantucket Island.
Spacey's former publicist said last week that the actor was "taking the time necessary to seek evaluation and treatment".
Vox has reached out to Spacey's representatives for comment. The allegations have led to his firing from the hit television series House of Cards by the streaming service Netflix, which has also refused to release a film in which Spacey stars as the late American writer and critic Gore Vidal.
