Marvel has a long history of bringing in directors who might not appear to be traditional choices to take the helm of a superhero movie. That tradition was upheld earlier this month, when we reported that filmmaker Taika Waititi, best known for comedy movies like What We Do in the Shadows and Eagle Vs. Shark, is in talks to direct Thor: Ragnarok. According to a new report from Birth.Movies.Death, the filmmaker was brought in to balance out Christopher Yost's script, which is said to be Marvel's darkest yet.

The report also essentially confirms a rumor that surfaced yesterday, which claimed that Mark Ruffalo's Hulk will have a prominent role in Thor: Ragnarok, alongside Chris Hemsworth (Thor), Tom Hiddleston (Loki) and Jaimie Alexander (Lady Sif). Hulk will reportedly have a major role, and the filmmakers want to accentuate the humor between Hulk and Thor, who are said to be going on a "cosmic road trip." Where exactly this road trip will take them remains to be seen, but it seems clear that Hulk will have a big role to play in Thor: Ragnarok.

The story has been rumored to center on the Norse Apocalypse, but no specific plot details have been given. This new report claims that Hulk and Thor will encounter the Valkyries throughout their journey, and that this movie could introduce the Marvel heroine named Valkyrie, a.k.a. Brunnhilde, as well. Valkyrie was first introduced in the Avengers comics, and she was also connected to The Defenders and Doctor Strange. Valkyrie's most notable enemy was The Enchantress, a character who may also be introduced on the big screen in Thor: Ragnarok. The report isn't sure if Valkyrie will be introduced as a stand alone hero, or if the Valkyries as a group will be shown as the beings who bring gods to Valhalla after they die.

With all of that being said, Marvel is hoping to cast some "great women" for roles in Thor: Ragnarok. While it isn't known if Taika Waititi has officially signed on yet, it's rumored that he may team up with another writer to add a comedic balance to Christopher Yost's script. We reported in August that Disney was considering filming Thor: Ragnarok in Australia, following the studio's great experience in the country while filming Pirates of the Caribbean: Dead Men Tell No Tales. While we still don't have any confirmed story details, Jaimie Alexander teased in July that elements in Captain America: Civil War will help set up Thor: Ragnarok.

Naturally, Marvel hasn't confirmed any details about Thor: Ragnarok, including any news about Hulk joining Thor, or how dark the script may or may not be. Would you like to see Thor and Hulk going on a humorous, cosmic road trip in Thor: Ragnarok? It isn't known when production will begin yet, but hopefully we'll hear more plot details very soon.
