He was also an associate producer for a 2013 film title 'Chapel Perilous'.

There's no summary to be found, but Googling the term brings up some interesting results. Wikipedia describes the term:

"Chapel perilous" is also a term referring to a psychological state in which an individual cannot be certain whether they have been aided or hindered by some force outside the realm of the natural world, or whether what appeared to be supernatural interference was a product of their own imagination. It was used by the late writer and philosopher Robert Anton Wilson (1932–2007) in his book Cosmic Trigger (1977). According to Wilson, being in this state leads the subject to become either paranoid or an agnostic. In his opinion there is no third way.

The third link from Google leads to this article

http://www.mindmined.com/public_library/nonfiction/anonymous_my_cosmic_trigger_finger_is_broken.html

The third sentence from that article reads:

"In researching occult conspiracies , one eventually faces a crossroad of mythic proportions (called Chapel Perilous in the trade). You come out the other side either stone paranoid or an agnostic; there is no third way. I came out agnostic."

So Mr. Alefantis has been a producer on TWO separate films, of which one has an inclusion of "secret pizza" in some respect, and the other is titled after a term used by by people who, in the very least, have some knowledge of the occult.

This hole just gets deeper and deeper...

Edit for formatting

Looks like he was an executive producer for a 2016 film 'Automatic at Sea', the summary of which reads:

On a whim, Eve, a young Swedish traveler, accepts an invitation from Peter to vacation on his family's private island off the coast of New England. As a series of unexpected delays prevent other guests from arriving, Eve discovers that she has little in common with the increasingly erratic Peter. Gradually the idyllic natural beauty of the island gives way and Eve finds herself trapped in a state of surreality punctuated by bizarre visions, dimensional shifting and secret pizza .

Not much else on the IMDB page...

I cant find a full plot description of the movie "Automatic at Sea" but in the summary it mentions "secret pizza" and another summary referred to hidden realms.
