3. Hulk Vs Thor
A live action movie based on the animated movie "Hulk Vs Thor" would be absolutely fantastic and it would allow Loki to achieve what he wanted to achieve in the Avengers movie and have Hulk doing his bidding. In the animated version of this story arc, Loki kidnaps Bruce Banner in his human form and takes him to Asgard with the help of Amora - once one of Thor's lovers and is who now the supervillain known as the Enchantress. Loki purposely makes Banner angry so that he changes into the Hulk and the Enchantress then casts a spell over him which sees Banner separated from his monstrous, green alter-ego and grants Loki control over the Hulk's body and mind. The God of Mischief then unleashes the Hulk on Asgard and he easily defeats the likes of the Warriors Three and several other Asgardian warriors, before Thor intervenes and they do battle. During the confrontation, Loki speaks to Thor through the Hulk's (alerting Thor to the fact that it is his adopted brother in control of the green powerhouse) and tries to pick up Mjolnir using the Hulk's formidable physical strength. He fails, of course, thanks to Mjolnir's enchantment and Thor manages to use his powers to separate the Hulk from Loki. This turns out to be a huge error on the God of Thunder's part, as Hulk proceeds to almost beat Thor to death without Banner's personality or Loki's control he really is a being of pure rage. A lot more goes on in this particular story, such as Bruce Banner dying and Thor having to travel to Hel to ask the powerful sorceress Hela to bring him back so he can merge with the Hulk again and get the beast under control, but the general plot is that Hulk attacks Asgard, which would be absolutely superb in a movie (it would look great and the mere idea of it is phenomenal).
