Snake in the Eagle's Shadow (1978)
One of the training scenes where Antonio Banderas is trying to hold himself up while Hopkins applies resistance with his legs while he is lying down next to him is a direct rip off of one of the training scenes in Snake in the Eagle's Shadow where Jackie Chan undergoes the same thing with Siu Tien Yuen applying the resistance.
The scene where The Bride slices her enemy's weapon to pieces is taken directly from 'Snake in the Eagle's Shadow'.
