Lambert made no order on costs.
Spacey was acquitted in 2023 of several criminal sexual charges alleged by four men following a trial in London.
Cannon – who was not involved in the 2023 case – also sued the Old Vic theatre, but settled that case out of court earlier this month.
Spacey won the best supporting actor Oscar for the 1996 film The Usual Suspects and best actor in 2000 for American Beauty.
But his once-stellar career was damaged by various allegations of sexual offences, which first emerged in 2017 as part of the nascent #MeToo movement, and which Spacey has always denied.
In 2022, a New York court also dismissed a $40 million civil sexual misconduct lawsuit brought against him.
