Actress Uma Thurman took the stand in New York Thursday in the trial of a man accused of stalking her, recounting how he had sent threatening emails to her parents, the New York Post reported online.

The "Kill Bill" and "Pulp Fiction" star told Manhattan Supreme Court that Jack Jordan, 37, who has been treated for mental illness, threatened to kill himself unless he could see the actress within a few days, it said.

Receiving no response, Jordan turned up at the set in Manhattan where Thurman was filming in November 2005 and tried to get into her trailer, before leaving a note under her door, the actress told the court, the Post reported.

Prosecutors say the man also turned up at Thurman's Greenwich Village home, where she lives with her two children, and rang the doorbell. An employee opened the door to find him sitting on the steps, MSNBC television reported.

"The fact that he had my parents' home number and had arrived at the set and come back when he was told to leave started to paint a picture much worse than some isolated moment," Thurman told the court, according to the Post.

She read out passages of the note left by Jordan, including one section suggesting "my hands should be on your body at all times," the newspaper said.

Jordan's lawyer, George Vomvolakis, told reporters that his client "may be obsessed, yes, but criminal? No," according to a video placed on the Post's website, adding: "He thought he was just being romantic."

Jordan was arrested in October 2007 and is on trial on charges of stalking and aggravated harassment. He has pleaded not guilty.
