True, the last stunt in RH was pretty big (the large drop and such), though it's not so much how big the stunt is, but the complexity and style in which it's carried off (like that vase balancing stunt which eventually ends in the vase being shattered by a stray round).
Did you know that Jackie Chan also sings? There's a CD "When Pigs Fly" that has a compilation of improbable re-makes of songs and has Jackie Chan singing a duet with Ani DiFranco ("Unforgettable"). He also sung in the Cantonese version of "Mulan" as the voice of General Li (no not the car in "Dukes of Hazard" or the Civil War general Goober ^_^). Maybe JLH and him could sing a duet. ^_-
BTW, You wouldn't believe what sort of mishaps during stunts have cost Jackie his health. As far as I can remember, he is partially deaf in one ear as resault of a bad landing.
