At the end of Avengers: Endgame, we saw Thor join the ranks of The Guardians of The Galaxy and that seemingly will be carrying over to Thor: Love & Thunder.
The Hollywood Reporter says that after Chris Pratt does some additional photography for The Tomorrow War he’ll join the production of Thor: Love & Thunder (working title The Big Salad) sometime next year in Sydney, New South Wales, Australia. Reprising the Peter Quill/Star-Lord role for the Thor sequel.
Love and Thunder is due to shoot in Australia in January, and Pratt will do a short round of additional photography for his sci-fi movie The Tomorrow War before heading to the land Down Under.
I have to assume the rest of the Guardians cast will being showing up as well.
