Two crew members of the ABC series "Lost" died of apparent heart attacks last week, according to the studio.
One crew member died after collapsing on the set and the other died while driving home from work. The series is filmed in Hawai'i.
The studio confirmed the two deaths but declined to discuss details.
"We are saddened by this tragic loss of life and our thoughts are with their families," said an ABC spokeswoman, who declined to be named.
