Actor Mark Harmon rescued two teenage boys Wednesday from a burning car that had crashed near his Brentwood home, a Los Angeles Fire Department spokesman said.
"Mr. Harmon broke out the car windows and pulled the boys to safety," said Brian Humphrey, a Fire Department spokesman.
"The youths owe their lives to the action of Mr. Harmon," he said.
One youth suffered severe burns over 30% of his body and was taken to UCLA Medical Center, Humphrey said.
The other youth suffered minor injuries and was taken to St. John's Hospital and Health Center.
The names of the youths, both 16, were not released.
About 7:15 p.m., the car in which the boys were riding missed a turn, crashed into a tree, flipped over and burst into flames in the 500 block of Bristol Avenue.
Harmon, who lives next door to where the car crashed, smashed the windows with a sledgehammer and rescued the boys.
Harmon, 44, a former UCLA quarterback, has starred in television shows such as "St. Elsewhere" and "Charlie Grace."
He also has been featured in a number of movies, including a TV movie in which he portrayed serial killer Ted Bundy.
