WhenAvengers: Age of Ultronhit theaters in May, the fate ofMark Ruffalo’s Hulk became one of the sequel’s biggest mysteries. The Green Goliath was last seen stealing a Quinjet, taking off for parts unknown. There were rumors thatHulkwould pop up in theMarvel Phase ThreeadventuresCaptain America: Civil WarandGuardians of the Galaxy Vol. 2, but they were never confirmed byMarvel. Today we have a new report fromJoBlo, which claims that Hulk will next be seen inThor: Ragnarok.

The site’s sources claim thatMark Ruffalowill joinChris Hemsworth(Thor),Tom Hiddleston(Loki) andJaimie Alexander(Lady Sif) inThor: Ragnarok, which will reportedly be set on a “distant planet” that is neither Asgard nor Earth. The site speculates thatMarvelmay be trying to work the long-rumored Planet Hulk storyline intoThor: Ragnarok, but that has yet to be confirmed. While the site won’t confirm the Planet Hulk rumor, they aren’t denying it either.

It also isn’t known how much we’ll see of Bruce Banner, as compared to his Hulk alter-ego, but it is believed that he will be prominently featured as part of the supporting cast. The story is said to center on the “Norse Apocalypse,” but no specific plot details were given. We reported in August that the studio may shootThor: Ragnarokin Australia, following Disney’s positive experiences in the country during the production ofPirates of the Caribbean: Dead Men Tell No Tales, but it isn’t known if that is confirmed, or when shooting may begin. Filming is about to get under way onDoctor Strangevery soon, withGuardians of the Galaxy Vol. 2set to follow in early 2016.

Speaking ofGuardians of the Galaxy Vol. 2, directorJames Gunnhas already shot down rumors of Hulk appearing in his sequel. The site claims that they may attempt to tease Hulk’sThor: Ragnarokrole into an end credit sequence inGuardians of the Galaxy Vol. 2, but that hasn’t been confirmed either. Even if this rumor aboutThor: Ragnarokis true, it isn’t known how they will explain how he went from a crashed Quinjet to a “distant planet.”
