Actually H.P. Lovecraft only wrote one tale about Cthulhu but others followed him, like Robert E. Howard, Robert Block, August W. Darleth. Many games followed as well and 'scary music' like Metallica's "The Call of Ktulu"

The HPL Historical Society has made some private, silent black & white movies on HPL's themes. Here (part of) their "The Call of Cthulhu" which some fan has added Metallica's "The Call of Ktulu" to.
