During the credits you can see on the left side of the screen rapidly appearing Chinese characters and English letters rotated 90 degrees clockwise. They are the tattoo that Talia has on her back and the translation, 'soy sauce'.
Just before the credits switch from Julia Roberts and Tom Hanks to rolling credits on black background, Roberts mouths 'Hi Mom'.
The Chinese characters and Soy Sauce translation appear again as the last logo displayed at the end of the credits just before the *fictitious* disclaimer.
Some of the roadsigns shown in the background don't have actual place names on them but words used in the movie, like 'Chilloot Park' (from a line said by Dean Tainot), or 'Break even paradox' (from a line said by Larry Crowne during Economics 1).
