Jessica Chastain, Queen of the Jungle? The overworked actress and recent Oscar nominee is said to be the first choice to play Jane in a new version of “Tarzan,” reports The Post’s Richard Johnson. Alexander Skarsgard is reportedly in the running to play the title character in the Warner Bros. reboot. In this story, the jungle boy is fully assimilated to life in London when Queen Victoria asks him to investigate troubles in the Congo. Samuel L. Jackson is rumored to play an ex-mercenary who helps Tarzan save the Congo from a vicious warlord. David Yates, who helmed four “Harry Potter” movies, will direct.
