Film 1010: Thor

Trivia: Stan Lee claims he'd always wanted to play Odin, but was happy with Anthony Hopkins's casting and performance in the role.

Jim Carrey was a long-time favorite and candidate for the role of Loki since The Mask, which indirectly featured Loki (but put in more fame his magic powers). Josh Hartnett was also rumored for the role.

Thor's armor is an amalgamation of the current Thor costume in mainstream Marvel continuity and the "Ultimate Marvel" comics universe.

It's mentioned in passing that Thor's hammer was forged inside "a dying star". This actually makes a modicum of scientific sense. When a very large star dies in a supernova, sometimes its remains collapsed to form a "neutron star". These objects cram the mass of the sun into the size of a city, forming a new kind of matter nicknamed neutronium. A single teaspoon of this material would weigh billions of tonnes. If Mjolnir was made of this material, it would certainly explain its incredible weight.

Dr Selvig mentions a comrade who got mixed up with SHIELD, whom he described as "a pioneer in gamma radiation"; this alludes to Bruce Banner, whose experiments in gamma radiation mutated him into the Incredible Hulk. A deleted scene also has him mention Hank Pym, also known as Ant-Man.

Brad Pitt was rumored for the role of Thor; Channing Tatum and WWE wrestler Paul Levesque (aka Triple H) was considered for the part; Daniel Craig was the first choice; and Charlie Hunnam, Tom Hiddleston, Alexander Skarsgård, Liam Hemsworth and Joel Kinnaman tested for the role, but finally Liam's brother Chris Hemsworth got the part.

Brian Blessed was rumored for the role of Odin.
