Today is the first time he has appeared in court after charges were announced in December.
Spacey, 59, is charged with attacking the 18-year-old son of former Boston TV news anchor Heather Unruh at the Club Car restaurant on the night of July 7, 2016.
Former "House of Cards" star Kevin Spacey will appear in a Nantucket court on Monday on accusations that he groped a young man in 2016.
Judge Thomas Barrett warned the gallery not to disrupt the proceedings with cellphones or electronics as Spacey peered around the room smirking.
Unruh's son told police Spacey had bought him several rounds of beer and whiskey and said at one point, "Let's get drunk", according to charging documents. Spacey nodded slightly when a judge asked if he understood. The teen told police that he sent his girlfriend a video of the incident, which she confirmed.
Amid other claims of assault or harassment - some at The Old Vic theatre in London where Spacey had been artistic director - he was dropped from House of Cards and other roles. If convicted, Spacey faces up to five years in prison.
After meeting the actor and telling him he was 23 years old - the legal drinking age is 21 in MA - he said he started drinking first beer and then whiskey with Mr Spacey at his urging.
However on Christmas Eve a video was released on his official Twitter account which appeared to feature the actor reprising his role as Frank Underwood from House of Cards, insisting: "I'm certainly not going to pay the price for the thing I didn't do".
"(Some people) have just been waiting with bated breath to hear me confess", he said, adding, "You wouldn't rush to judgment without facts, would you?"
Spacey, who filed the motion to waive his appearance under his legal name Kevin S. Fowler, said he intends to plead not guilty.
More than 30 men have said they were victims of unwanted sexual advances by Spacey, who became embroiled in controversy after actor Anthony Rapp in October 2017 accused him of trying to seduce him in 1986 when Rapp was 14. "Only you and I both know it's not that simple, not in politics and not in life".
