Thor is in trouble.
The teaser trailer for "Thor: Ragnarok," with a thumping soundtrack courtesy of Led Zeppelin, dropped Monday morning.
It finds our favorite Asgardian imprisoned without his hammer on the planet Sakaar. Thor finds himself in a race against time to get back to Asgard to stop Ragnarok -- the destruction of his home world and the end of Asgardian civilization -- at the hands of an all-powerful new threat, the ruthless Hela (Cate Blanchett).
Unfortunately, Thor must first survive a deadly gladiatorial contest that pits him against his former ally and fellow Avenger, the Hulk.
"Thor: Ragnarok" will be released in theaters Nov. 3.
