The R-rated movie, which was directed by David S. Ward, was released last month by Touchstone Pictures, a division of the Walt Disney Studios. Touchstone Pictures released a brief statement tonight offering condolences to the families, but it defended the film. "The scene in 'The Program' clearly depicts this adolescent action as an irresponsible and dangerous stunt by a troubled and heavily intoxicated individual, and in no way advocates or encourages this type of behavior," the statement said. "This is a tragedy and our sympathies go out to the families of those involved."

In the Pennsylvania case, the police said the driver of the pickup truck did not see the boys, who were wearing dark clothes and were lying in the center of the road, parallel to the yellow line dividing the lanes. "I was told they did this as a dare," Trooper David Wargo, the investigating officer, said on Sunday. As many as four teen-agers were lying on the road at one time, the boys told the police. Neither the driver of the truck nor any of the other drivers involved in this spate of accidents was charged with any violation.

"As a parent," Ms. Shingledecker said, "I know that 95 percent of what gets on TV or in the movies gets into kids' heads. Why are they putting these movies out for our children?"

She said that her son graduated from high school last year and had planned to enter college in January to study criminology. He had hoped to become an agent for the Federal Bureau of Investigation.

In the Long Island accident, a 17-year-old girl told the Nassau County police that she was driving her 1987 Plymouth westbound on Bayville Avenue east of West Harbor Drive. The area, which has a large parking lot for summer beach traffic, has long been a gathering place for young people. Theycruise along the road, park along the beach and gather in small groups to sip beer and "hang out," Mr. Ketaltas said.

He said the teen-age driver reported seeing a group of 50 to 75 young people standing on either side of the avenue. She said she slowed down as she passed the group, then struck something in the road. She said she did not know until later that she had struck Mr. Macias, a football player and a senior at Syosset High School. Account From Witness

Mr. Ketaltas said it was not clear whether the injured teen-ager had been lying on the yellow double line in the middle of the two-lane road or in the middle of the westbound lane when he was struck.
