Thor: Tales of Asgard (2011)

Before the hammer ... came the sword

Hungry for adventure, Thor secretly embarks on the journey of a lifetime, joined by his loyal brother Loki, whose budding sorcery equips him with just enough magic to conjure up trouble, along with the Warriors Three - a band of boastful travelers reluctant to set sail on any adventure that might actually be dangerous. But what starts out as a harmless treasure hunt quickly turns deadly, and Thor must now prove himself worthy of the destiny he covets by saving Asgard itself.
