Giving evidence, the Hollywood star denied being a sexual bully and labelled the prosecution’s case against him as “weak”, accusing one alleged victim of being after “money, money and then money”.
He told the jury the sexual assault allegations were “madness”, “made no logical sense” and were a “stab in the back”.
During proceedings, Mr Spacey had told jurors he could have had sex “all the time” but found it hard to trust people because of his fame.
Asked if he considered himself to be a powerful man, he replied: “I did not have a power wand that I waved in front of people’s faces whenever I wanted someone to go to bed with me.”
The court heard how Mr Spacey, who is an American citizen, had moved to London in 2001 to take up a role as artistic director at the Old Vic theatre.
But during his time in the UK he was accused of attacking four men aged in their 20s and 30s.
Prosecutors alleged that Mr Spacey’s “preferred method of assault” was to aggressively grab other men by the crotch.
He was also accused of performing a sex act on an aspiring actor who had passed out in his Waterloo apartment.
Mr Spacey was acquitted of seven counts of sexual assault, one count of causing a person to engage in sexual activity without consent and one count of causing a person to engage in penetrative sexual activity without consent.
Following the not guilty verdicts in the Kevin Spacey trial, the Crown Prosecution Service (CPS) said prosecutors “respect” the decision of the court.
In a statement, a CPS spokesman said: “Following a thorough investigation by the Metropolitan Police, the CPS made the decision to charge Kevin Spacey with sexual offences.
“The function of the CPS is not to decide whether a person is guilty of a criminal offence, but to make fair, independent and objective assessments about whether it is appropriate to present charges.
“It is the role of the jury to consider the charges and we respect the decision of the court.”
