The early glimpse was tweeted from Landau's account, illustrating a rough drawing of the face of a female Avatar character with the caption "Avatar 2," according to The Hollywood Reporter.
In the past, filmmaker James Cameron said that "Avatar 2" will be the first of three sequels, with Zoe Saldana and Sigourney Weaver reprising their roles.
"Avatar" that became the highest-grossing film of all time replacing "Titanic" revolved around humans, who controlled half human/half alien Avatar hybrids to explore the fictional universe Pandora.
