Controversy surrounds the Barbie movie due to a scene featuring a disputed South China Sea map.
The Philippines and Vietnam may ban the movie for including the contentious nine-dash line.
The movie is currently under review by the Philippines' regulatory board.
A senator is urging a block on the film, citing sovereignty concerns.
Warner Bros. defends the map as a "child-like" doodle with no political statement.
The territorial claims in the South China Sea are complex and overlapping.
The inclusion of the nine-dash line is viewed as endorsing China's claims, causing outrage.
Editing the map out of the movie is proposed as a potential compromise.
