'Cast Away'

In the 2000 film "Cast Away," American actor Tom Hanks showed everyone the stark and lonely reality of being marooned on a Pacific island. Imaginary volleyball friends aside, it's not something we would want to attempt.

Directed by American Robert Zemeckis, the movie is notable not only for its intimate cinematography, but also for its limited use of a soundtrack or sound effects. According to Zemeckis, this absence was intentional so as to reinforce the feeling of isolation.

The film was nominated for two Academy Awards: Best Actor and, ironically, Best Sound.
