I'm looking for a film from years ago that was about a kid that was kidnapped and one the kidnappers was really kind to the boy that they had kidnapped and at the end in an identity parade, the boy picked out the wrong man on purpose because he was kind..

Does that ring a bell to anyone?

There is a similar movie called A Perfect World (1993)
With Kevin Costner, but the ending is different. But check it out just in case. A Perfect World (1993) - IMDb (http://www.imdb.com/title/tt0107808/)
