In Peter Weir's thriller Witness, a young Amish boy witnesses a murder in the restroom of a Philadelphia bus station. John Book (Harrison Ford), the police detective investigating the murder, discovers that the crime was part of a conspiracy involving several officials in his department. Book flees Philadelphia to the Amish community where the boy lives with his widowed mother (Kelly McGillis). Book slowly assimilates himself into the Amish community, falling in love with the boy's mother in the process. Eventually, the corrupt police track Book down, and he is forced to confront them, while protecting the boy and his mother. Witness is as much a love story as it is a thriller, and the film is very successful at operating on both levels, due to Ford's wonderful, textured performance and Weir's assured direction. Furthermore, Witness is one of the rare movies to accurately evoke the Amish lifestyle without being condescending, making a terrific film all the more rich and exciting.
