Karen Gillan aka Nebula has no idea what 'Avengers 4' is aboutOct 29 (AZINS) Karen Gillan says she is clueless about the plot of Avengers 4.

The actor, who plays Nebula in the Marvel Cinematic Universe, says directing duo Russo brothers have taken extreme measures against leaks and plot spoilers.

"We didn't even get a script, there was no script. Just my scenes. I'd sometimes get them just in the morning, do them, hand them back over at the end of the day.

She even claimed she does not know the title of the film, which is set to release on May 3, 2019.

The actor has finished shooting for the movie.

Gillan has appeared as Nebula in Avengers: Infinity War and the two Guardians of the Galaxy films.
