This highly anticipated film brings together Iron Man, The Incredible Hulk, Thor and Captain America and friends (including Nick Fury and Black Widow) to save the world from Loki, Thor’s bitter brother who has stolen the Tesseract, a blue cube that gives its bearer unlimited power and a portal to outerspace. Director/screenwriter Joss Whedon (Thor, Serenity) deftly balances all these superheroes, giving each a time to shine while also having a lot of smart and fast-paced fun with the story.
