Sky Captain and the World of Tomorrow Easter Egg - More King Kong

At the point in the film where Sky Captain and the British amphibious squadron have just entered the water (1:05:28 on my DVD) they pass over several shipwrecks. The first of these is seen to have the name Venture on its bow, the name of the ship from King Kong. As they pass over that ship you can briefly see a large cage on its deck that has clearly been broken out of.
