"It isn't replacing. In a amusing way it's starting all over again because it's going to be different, naturally", Plummer toldEntertainment Tonight.
'I think it's very sad what happened to him, ' Plummer told Vanity Fair. 'Kevin is such a talented and a terrifically gifted actor, and it's so sad. It's such a shame. "That's all I can say, because that's it". "Although the situation is very sad". "But I've got to forget that and go and do it, because it's a very well-written script and Ridley has been very good".
One user, Charlotte Arkell, said she was: 'Absolutely disgusted and ashamed of Plummer'.
While another vented that the victims deserved sympathy and that Spacey was the perpetrator.
Plummer said Scott called him last week to offer him the part.
A Twitter hashtag dubbed #ReplaceHimToo also began to gain traction following the interview.
Scott had dropped Spacey from his upcoming film "All The Money In The World" in wake of multiple allegations of sexual misconduct and harassment against him.
Plummer was revealed as the man to replace Spacey as billionaire oil tycoon Jean Paul Getty (centre) in "All The Money In The World", with Scott reshooting all of Spacey's scenes at a cost of millions to the production company. It's starting all over again'.
The film follows Getty's grandson John Paul Getty III, who was kidnapped by an organised crime regime, and his mother Gail's (Michelle Williams) attempts to convince his wealthy grandfather to pay the ransom.
