Guillermo Del Toro

The new issue of the New Yorker magazine has a long feature on the movie director Guillermo Del Toro, with a description of his man cave that he calls "Bleak House," with a collection of fantasy art that rivals that of his hero Forrest Ackerman. 

 
On the walls beside him are eerie antique portraits by Travis Louie, who didn't seem to be credited. The article mentions the ups and downs of development work on New Line's Hobbit (which, alas, Del Toro didn't end up directing), his work on Frankenstein (with a mention of illustrator/concept artist Bernie Wrightson), and Del Toro's recent work on the Lovecraft story "At the Mountains of Madness" with concept artists Allen Williams, Peter Konig, Wayne Barlowe, Keith Thompson, and Guy Davis.
