"Big" failed at finding Tom Hanks' Doppleganger

In 1988, the movie Big debuted with Tom Hanks playing an older David Moscow.  At the time of filming David was 14 years old and Tom was 32.  After seeing this movie this past weekend on cable television, enough time had passed that I was curious to see if David Moscow turned out to look anything like Tom Hanks.  Here are the results:

David Moscow at 14 and Tom Hanks at 32

At first glance I would say that the casting director made a decent attempt at finding a younger version of Tom Hanks.  Both have dark, wavy hair and they have similar eyes and ears.  The key difference seems to be that they have very different facial bone structures.  You can already start to see David's chiseled jaw bone which is not even close to Tom's softer lines.

Take a look at David in September of 2006, just a couple months before his 32nd birthday.  If these two entered a doppleganger contest - they shouldn't even get the obligatory participation ribbon.

Update - I added another image of David at age 33 as the first image was not showing up in all browsers.
