Jane March Horwood is an English film actress and former model.

At age 14, March won a local "Become a Model" contest. She signed with Storm Model Management and began working as a print model using her middle name March, which was also her birth month.

After being spotted on the cover of Just Seventeen by French director Jean-Jacques Annaud, she was chosen to play the female lead in his film The Lover (1992), based on a semi autobiographical novel by Marguerite Duras.

Two years after The Lover (1992), she co-starred with Bruce Willis in the erotic thriller Color of Night (1994), directed by Richard Rush. She later said, "I didn't like the script at all, but it was a Bruce Willis film and I wasn't going to turn it down".

While Color of Night (1994) was in production, March began dating the film's co-producer Carmine Zozzora. The couple married in June 1993 in an 11-minute ceremony at which Bruce Willis was the best man and Demi Moore was the maid of honor. They separated in 1997 and finally divorced in 2001.
