Forget about the mysteries of God and religion explained in The Da Vinci Code, the real conundrum of the universe this summer movie season is how Tom Hanks never changes. The guy has been acting since the early 1980s and now more than 25 years later, he still looks like he did back on Bosom Buddies, especially with his long hair. He plays a good guy in one movie, a bad guy in another, and he looks identical. Modern, period, Southern, foreign -- it's all just Tom Hanks. How does he do it? He'll never give that away. For a little fun, we thought we'd see how good you are at spotting Tom through the years in his many ages and his many roles.
