While filming Color of Night (1994), opposite Bruce Willis, she fell in love with one of the film's producers, Carmine Zozzora. Just two months after their first date, he proposed on May 6, 1993 and they flew by private jet to Lake Tahoe, marrying in the Dream-Maker wedding chapel on June 14. She was only 20, he was 35 and a Hollywood millionaire hotshot. They were married in a hurry during an 8-hour break from filming Color of Night (1994). March wore a white t-shirt and jeans at the 11-minute ceremony. Friends Bruce Willis and Demi Moore were the witnesses; Willis was also the best man and Moore was maid of honor. Instead of having a honeymoon, March went back to filming Color of Night (1994). Besides being a producer on the film, Zozzora was also the head of Bruce Willis' production company Flying Heart. After they were married, Zozzora put March in another film, the 1996 spy thriller Provocateur (1998) for which he was executive producer. After a whirlwind marriage, the two separated in 1997 and finally divorced in 2001.
