A ton of productions are based on Lovecraft stories and movies. Jeffrey Combs starred in 2 "Re-Animator" movies based on a Lovecraft novel.
There was a TV movie from 2001 that was very loosely based on the Lovecraftian character Dagon (Lovecraft's hard-core fans hated this movie).
According to
IMDB, quite a few productions owe something to Lovecraft.
Some science fiction and fantasy movies and TV shows also borrowed ideas from Lovecraft.
