Avatar sequel to 'go underwater'

Rodriguez, 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 Cameron, who helped produce the 3D underwater cave adventure Sanctum.

Rodriguez has been promoting her latest film Battle: Los Angeles about aliens attacking California.
