At just 9 years old, Raushan Hammond was too young to be intimidated when costar Robin Williams encouraged him to improvise some of his lines.
“There were lots of parts of the movie where there was no script, and we would have to go with the flow and see what Robin would do,” says Hammond, now 32, who played one of the Lost Boys in 1991’s Hook.
“He was always encouraging me,” he adds.
