When Raju is playing with the Game Boy you can hear music from Tetris, but it's actually not turned on at all.
Early in the movie, when Kenpo and the 3 other Tibetan monks are driving north on the top level of WA-99 the movie cuts to a separate shot of the same group now traveling north on Interstate-5 and then again south on the lower level of the WA-99 viaduct. However, as the scene continues, the group ends up atop the Queen Anne neighborhood, which is a northern part of Seattle.
