According to court documents obtained by Radar Online, McLanahan has claimed that he came up with the concept of the movie when he wrote the screenplay titled 'Head On' in 1998. McLanahan has alleged that after submitting the script to the US Copyright Office, 'Head On' received a copyright certificate protecting its material and author from unauthorized use.
