Should movies make money, then the Hollywood rule of thumb is to
make another, and another, until the franchise runs out of steam.
The original Rush Hour was a Jackie Chan vehicle of sorts to break
into Hollywood, and it made a lot of money with the mis-pairing
opposite Chris Tucker in a buddy cop movie formula filled with
action and comedy. Rush Hour 2 was made 3 years later and made even
more money, but it took 6 years for the second sequel to be made,
and 9 years for the entire trilogy to be done (pray tell, will
there be another sequel?)
