2. Road to Perdition
3. The Polar Express (a cartoon film where he was the voice of the ticket collector)
4. The Terminal
5. Catch me if you can
6. Cast Away
I have excluded the hugely popular Sleepless in Seattle as I am yet to watch it. Some other films, which were critically acclaimed are also missing from my list (like Forrest Gump and Saving Private Ryan) as I wasn't too impressed with the overall presentation.
So, here's hoping that Tom Hanks will continue to enthrall us by his stupendous performance on screen.
