New York- ACTOR/director Vincent Gallo has turned his famously venomous tongue on “Spider-Man” sweetie Kirsten Dunst.

The “Brown Bunny” bomb-thrower claims that Dunst left him in the lurch two years ago when she dropped out of the controversial arthouse flick the day before she was supposed to shoot her scene.

Gallo tells us that when he called Dunst and “expressed to her that I was displeased that she had abandoned me on the day she was supposed to film,” she “became another person – she was a cold, curt, nasty little witch of a brat on the phone.”

Gallo said it all began when Dunst approached him at a Vanity Fair Oscar party and told him how much she loved his movie “Buffalo 66.” The two soon struck a deal that Dunst would briefly appear in the beginning of “Brown Bunny.” But the day before she was supposed to fly to New Hampshire to perform in her scene, Gallo says, Dunst’s agent, Theresa Peters, informed him she was backing out.

Peters tells us Dunst’s people had to veto the role when they realized Gallo’s guerrilla-style shoot was not abiding by Screen Actors Guild guidelines. “When the deal came over and the lawyer saw that it was not SAG-signatory, we said, ‘She can’t do this,’ and he went ballistic,” Peters relates. “He can say anything he wants. She did nothing wrong.”

Looking back, Gallo tried to take the high road, sort of. “I understood where she was coming from; maybe she [accepted the role] too soon,” he said.

He continued, “If she wants to do lame, stupid movies, it’s great, I respect her … I was very angry for a really long time, but at this point I just think she’s a talented, pretty person and I only wish good things for her.”

Lest Dunst have hurt feelings over the incident, she might want to recall Gallo’s history of trashing his fellow celebs.

On actor Tim Roth, Gallo once said: “Tim Roth is like holding a penis upside down to make it appear erect.” On his “Buffalo 66” star Christina Ricci: “I don’t like her. But it’s OK. She’s basically a puppet. I told her what to do, and she did it.”

And who could forget his feud with critic Roger Ebert, on whom Gallo put an “unremovable black magic curse” that would give Ebert colon cancer?

When Ebert later contracted cancer of the salivary gland, Gallo was dubbed “Vinnie Black Magic” by pals.
