Kirsten Dunst has a lot to be thankful for this holiday season—including a brand-new restraining order against an alleged stalker.

The Spider-Man star took the action after one Christopher Smith allegedly showed up unannounced at her Hollywood Hills home, most recently on Nov. 20. While there, she states in court papers, he exhibited "aggressive" and "harassing" behavior, while claiming "he has some sort of spiritual connection" with her even though they have never met.

"Mr. Smith has repeatedly shown up uninvited at my place of residence in Los Angeles, going so far as to ignore police warnings, bypass my personal security measures, trespass on my property, and attempt to gain entry into my home," Dunst says in her declaration.

LAPD confirmed that officers responded to a pre-Thanksgiving 911 call about an unidentified intruder at her canyon residence.

"On Nov. 20, 2008, there was some sort of a call and police went to her home," a police spokeswoman tells E! News. However, LAPD had no immediate information on any charges being filed.

Dunst was not home when the incident occurred, but it got her Spidey senses tingling in all the wrong ways.

"Mr. Smith's sudden, aggressive and harassing efforts to contact me are extremely frightening," she continues in her declaration, filed Nov. 26 in Los Angeles Superior Court. "I fear not only for my own personal safety, but also for the safety and well being of my housemate and assistant.

"Given his delusional belief that he has some sort of spiritual connection with me and his apparent willingness to ignore security measures, requests to leave me alone and police warnings," she says, "I believe Mr. Smith will continue to engage in this behavior, and that this behavior will only escalate, unless and until he is ordered by this court to stop."

Such an order would force the Los Angeles native to stay at least 200 yards away from Dunst, her family, personal assistant, and her property. He would also be forbidden from owning or possessing a firearm.

The filing also includes a declaration by Billy Durney, a private security guard employed by Dunst. He asserts Smith repeatedly ignored police warnings not to encroach on her property, prompting authorities to take him into custody at one point and place him "in a 72-hour psychiatric hold."

According to arresting documents, Smith told police at the time “I’m in love with Kirsten, so I went to her house…I connected with Kirsten spiritually. I felt like I connected with her and she connected with me. Now I don’t know if she did. I guess you have to ask her if she connected.”

No further information about Smith was available. Entertainment Tonight  quotes unnamed sources as saying this is not the first time he has come calling.

As a precaution, the actress, whose neighbors include American Idol host and E! News anchor Ryan Seacrest, has reportedly beefed up security at her pad as well as around her mother's house in nearby Toluca Lake, just north of Hollywood.

The court will decide whether to grant the star a permanent restraining order at a hearing scheduled for Dec. 22.

Dunst would presumably prefer to focus on her day job than intruders. She next appears on the big screen opposite Ryan Gosling in the romantic mystery All Good Things, due out early next year, and she's said to be reprising her role as Mary Jane Watson in Spider-Man 4, now in preproduction.
