Continuity mistake: When the city takes off it is surrounded by land. However while it is flying it is suddenly over a large body of water, but when it crashes back to the ground it is over land again.
Trivia: When all the Avengers are attempting to lift Thor's hammer, Captain America is able to move it slightly. In the comics, Cap is one of the few characters noble enough to be able to lift Thor's hammer (notable others being Storm and Beta Ray Bill).
Trivia: Stan Lee makes his customary appearance whilst the Avengers and a load of War Veterans are enjoying a get together. Thor offers a 1,000 year old Asgardian drink to Captain America, and Stan Lee asks for some.
Question: Nothing very spoilery! The pool that Thor goes to with Erik Selvig - did I miss something, or was that just not explained much? It seems like he meets Erik, then they both go directly to a mystical lake in a cave that Thor just randomly happens to know about.
