Bonham Carter's relatives were on a safari holiday in the country when a minibus they were traveling in on Wednesday spun out of control and flipped over after a tire burst.

The actress' cousin Fiona Bonham Carter, 51, escaped with a broken shoulder. But Fiona's son Marcus Egerton-Warburton, 14, her mother Brenda, 74, and stepfather Francis Kirkwood, 75, all died.

Fiona's sister-in-law Kay Boardman, 54, also perished in the crash, in a remote area six hours' drive from Johannesburg. Bonham Carter has now been granted indefinite leave from the set of Terminator Salvation in Albuquerque, New Mexico to fly back to the U.K. to comfort her distraught family.

A source tells British newspaper the Sunday Express, "Everyone here was in a state of shock when the news came through. I saw an assistant of Helena's who told me she is absolutely stricken with grief. She can't believe what happened."
