Films that are similar to ours - Childs Play -

 

Childs Play is a 1988 American Horror film written by Don Mancini and Directed by Tom Holland.
The plot of the film revolves around a serial killer who goes by the name of Charles Lee Ray. Knowing he cannot escape being chased, he hides in a toy store and uses a voodoo ritual to transfer his soul into one of  the dolls that he had found.
The store is then struck by lighting and burns down although the dolls survive. Later that morning, 6-year-old Andy Barclay tells his widowed mother Karen Barclay that he wants a Good Guy doll for his birthday. Unable to afford the full price, Karen buys a stolen doll from a street peddler, which is the same doll into which Charles Lee Ray had earlier transferred his soul.

This film is similar to ours as once again, the main character is a child who is placed in a phsychiatric ward due to his story about the doll, 'Chucky'  that his mother thinks has affected his mental health. The main reason this film is similar to ours is because his Mother thinks that her son has got a mental problem which our main character in our film, Damien most certainly has.
