Actress Michelle Rodriguez has said Avatar 2 will take viewers underwater and will be extraordinarily beautiful.
Michelle, who starred in the original, said she has no clue yet whether she will be asked to play a role in the sequel.
But she said she hopes creator James Cameron will at least invite her to the set to watch it being made.
Going underwater seems to be a running theme for James, who helped produce the 3D underwater cave adventure Sanctum.
Michelle has been promoting her latest film Battle: Los Angeles about aliens attacking California.
Michelle, who plays an Air Force sergeant, said the film pays homage to troops.
