Lucy Gordon, a British actress who appeared in "Spider-Man 3," was found dead in her Paris apartment after apparently committing suicide, the French police said Thursday. She was 28.

An autopsy has been ordered to determine the cause of death, though it appeared to be a suicide, said an official with the Paris police headquarters. The official, who spoke on condition of anonymity because of a police agency policy, gave no details.

Ms. Gordon, who would have turned 29 on Friday, appeared in a dozen films. In "Spider-Man 3" she played the reporter Jennifer Dugan. In a forthcoming biopic about Serge Gainsbourg, she portrays the British singer and actress Jane Birkin.

Speaking from the family's home in Oxford, Ms. Gordon's father, Richard Gordon, told Britain's Press Association that his daughter was "a natural actress all her life, since she was about 2."

"She's always loved being on stage and in front of the camera and she has kept all her naturalness and charm all the way through," he added. "She has been the most beautiful daughter. We are obviously devastated."

He added that his daughter spent much of her childhood and her summer vacations in France and was bilingual. She recently moved to Paris after living in New York.
