Kevin Spacey is on trial at Southwark Crown Court in London, accused of a dozen allegations of historic sex offences committed against four men between 2001 and 2013.
The first of the alleged victims testified that Spacey had assaulted him on up to 12 occasions, grabbing his "private areas" when they were alone, and that Spacey had tried to "groom" him before later repeatedly groping him.
The accuser described Spacey as a "slippery", difficult person and a "mixed-up individual" who was very confused about his sexuality.
The trial is due to last about four weeks.
