A celebrity-obsessed loner “terrified” actress Uma Thurman by flooding her with phone calls and e-mails, ringing her doorbell at all hours, and threatening to kill himself if he couldn’t meet her, a prosecutor said yesterday in closing arguments.

“This isn’t about love for Uma Thurman,” an assistant district attorney, Jessica Taub, told jurors. “This is about self-absorption.”

Jack Jordan, 37, is on trial in state Supreme Court in Manhattan on charges of stalking and aggravated harassment; he faces up to a year in jail if convicted.

The jury began deliberating yesterday afternoon before leaving for the day. They were expected to resume this morning.

Defense lawyer George Vomvolakis conceded in his closing argument that Mr. Jordan’s behavior was obsessive, but said his client did not have criminal intent to scare or harass the “Kill Bill” and “Pulp Fiction” actress.

“He’s trying to get to the woman he loves — although it’s an obsession — in the hope that she will love him back,” Mr. Vomvolakis said.

“Jack Jordan is not charged with obsession. Obsession is not a crime.”

Mr. Vomvolakis also complained that the case went to trial only because a celebrity was involved.

But Ms. Taub countered by saying that Mr. Jordan’s actions indicated his intent to hound or harass anyone who stood in his way because “he wanted to be with Uma Thurman and he would not take no for an answer.”
