Revealing mistake: After Bluto knocks Popeye out and he falls into the water, Bluto goes to jump in after him. Watch the water. Popeye just landed, but the water is really calm. And when Bluto hits the water, it's right on top of a face-down floating Popeye. As Bluto hits, Popeye's body bends almost in half backwards, revealing that it's a foam rubber mannequin.
