Scottishmummy Malachi is the correct spelling - he was a prophet and a saint - means 'my messenger' or 'my angel'. It can be spelt Malachy also and is within the catholic church, i beleive, but the original Hebrew spelling is with 'i'.
Children of the Corn is a very scary nightmarey horror film by Stephen King.
And i have just googled some pictures and I have seen it, i was very young and I remember the scarey image of a house on the edge of a corn field. I remember having nightmares about not escaping! I do not recall much about it other than terrifying and luckily NOT the name Malachi
