The man, who remains unidentified due to British law, testified in a London courtroom on Wednesday, recounting his experience with Spacey during the early 2000s when the actor served as the artistic director of London's Old Vic Theatre.
According to the accuser, Spacey subjected him to a barrage of sexual and racial verbal abuse before forcefully grabbing his crotch backstage.
Describing the incident, the alleged victim stated, "It wasn't like a caress. It was like a cobra coming out and getting hold. Not like a seduction. It was angry."
During cross-examination on Thursday, Spacey's lawyer, Patrick Gibbs, challenged the credibility of the man's account, asserting that many aspects of his story were "completely untrue."

The man also refuted Gibbs' suggestion that he sought to "monetize" his knowledge of Spacey, emphasizing that he felt "degraded" and "worthless" as a result of the incident.
When asked why he did not immediately come forward, the accuser explained that Spacey was regarded as the "shining light of the West End" and expressed concerns that speaking out would make him the "problem."

Defense attorney Patrick Gibbs denied all allegations of nonconsensual activity and urged the jurors to carefully consider the evidence presented.

The trial continues, with further testimony expected from the remaining accusers.
