Errol Morris, the documentary film maker has found
a creepy crossover between 50s SF classic
This Island Earth and Douglas Sirk's 50's soapie movie,
Imitation of Life. (Thanks to Gary Farber's blog
Amygdala for the heads up on this one.
Of course, this isn't Douglas Sirk's only genre crossover. In the Kim Newman/Jack Yeovil novels set in the Warhammer universe, there's a theatrical director/playwright/actor called Detlef Sierck, which just happens to be the original name of Douglas Sirk. There' also a
László Löwenstein in them, too. Newman has written extensively, and wittily about movies and probably writes more in-jokes into his fiction than any three other authors.
