Back during filming in New York, a call sheet was leaked for Disney & Marvel Studios' The Avengers, revealing vague details about a "Levathan," which was soon after confirmed to be a CG creation.
Before I continue, I am putting a SPOILER WARNING! If you don't want to know anything about Leviathan, please, don't read anything below.
Last month, a New York shooting schedule was leaked online revealing some big action sequences. The most intersting part was something about mysterious Leviathan, which caused a big discussion. Some said it might be an alien ship, maybe a part of the big camera that is used for filming but there was also an article where someone mentioned via Twitter that "Leviathan" is actually a sea-monster. Well, a source close to the production of the Joss Whedon-directed film, who've provided reliable scoops in the past, shared some brief details about it.
