The Movie: Hide And Seek (2005)
The Kid: Emily Callaway (Dakota Fanning)
Fanning is Emily, the withdrawn daughter of recent widower David Calloway.
Already traumatised by the suicide of her mother, Emily retreats into a world of her own.
She soon admits to her father that she sees an imaginary friend called "Charlie" who eventually starts murdering people.
Spoiler Alert! There's a twist - Emily is not the dangerous one. It's Bobby D, who has a split personality.
The Scene They Probably Weren't Allowed To Watch: Fanning can stand most things, but she probably wasn't shown the bloody discovery of De Niro's wife's suicide.
