How is the asian guy in Fast Five still alive if he died in part 3?
The movies are not in chronological order. Han does in fact die in tokyo but fast five takes place before tokyo drift. The order is:
The Fast and the Furious
2 fast 2 furious
fast and furious
fast and furious: tokyo drift
Rumors on a sixth movie is going around too. It's highly likely because at the end of fast five when han (asian guy) is in the lexus lfa Gisele (girl who worked for braga) asks him if he wanted to go to tokyo. He said "we'll get to tokyo eventually" and they were heading to madrid I think.
during the casino scene towards the end of fast five, did the two spanish guys lose their 10 million dollars?
It is unresolved. It kind of reminded me of the last scene of Inception.
The one placed his bets on red, the other on black, but it looked at the last second as if it was about to land on green. Guess we won't know until the next movie... if they ever even tell us.
