H. P. Lovecraft Historical Society

HPLHS produces a number of Cthulhu Mythos films, including the eponymous The Call of Cthulhu (horror film adaptation of H. Lovecraft's short story of the same name), as well as sound recordings, under its Mythoscope and Mythophone labels, respectively. They also offer props, both for sale and for free download. Originally a hobbyist group, HPLHS has become a for-profit company dedicated to creating content faithful to the spirit of the Gothic 1920s source material but leavening it with some humour. The HPLHS is the world's largest organization of Lovecraft enthusiasts, with members in more than fifty countries.
