Tom Hanks' co-star didn't know who he was!

Tom Hanks' co-star has never seen any of his movies.

He starred alongside 12-year-old Helen Zengal in 'News of the World' and said he would spend their time on set quizzing her about his movies but she did not know a single title.

Hanks plays Captain Jefferson Kyle Kidd, a widower and veteran of three wars in the post-Civil War drama.

It marks the first time Hanks stars in a western movie but he insists he has taken a more serious approach to the movie than portray a "rootin' tootin'" cowboy.
