Step 4 in the Avengers process proved to be the toughest. How does Marvel make a movie about a god of thunder that moviegoers can understand and comic book fans can still enjoy? Last year's "Thor" was under some heavy scrutiny during the early stages of production, but it came through in a big way at the box office. Another fantastic ensemble cast for Marvel here...Chris Hemsworth, Natalie Portman, Anthony Hopkins, Tom Hiddleston and more. "Thor" was the first Marvel movie to be released in 3D. Director Kenneth Branagh brought us all into Asgard for the very first time and it was a visual treat. The movie does a great job of keeping things simple. It doesn't try to have too much going on at once or overdo any of the action sequences. Some of its best parts occur when Thor and Jane (Natalie Portman) are on their adventure. "Iron Man 2" first introduced us to Black Widow. "Thor" introduces us to Hawkeye. Jeremy Renner plays the famous bow and arrow assassin, and although he doesn't do much in the film, it's just enough to plant the seed and make you want to see more. For a nice change of pace from some of the other superheroes, pop in "Thor" and you'll see that even gods can make for good, clean, fun.
