[The_Return]

Not nearly as familiar with him as I'd like to be (strongly considering picking up the new boxset of his work), but based on what I've seen my favourite has to be the original House on Haunted Hill, followed closely by The Tingler.

You hit the nail on the head as far as why I enjoy them so much...his films might not always be scary, but he had such a great sense of fun and adventure that translated perfectly onto the screen. You can tell in every frame that he was genuinely passionate about his art and that he lived to entertain.

One of the genre's finest directors, based on my experience. Pure, unadulterated entertainment.
