It was filmed up in Lone Pine, halfway between the Valley and Mammoth Lake, about a three hour drive, so we stayed up there. We shot it in the Spring… - Virginia Grey

Hollywood men are a lot of phony balonies.

I don’t believe it. You know, after a picture’s been out for awhile, stories seem to circulate—stories that can no longer be verified, because everyone connected with the incident is dead. People will say anything to sell a book. As for our work with the dinosaurs, it was all done with a backscreen, so none of the actors saw the monsters, until we saw the picture. I liked doing it! It was a crazy picture, and I liked working with Richard Denning and Barton MacLane. They dyed my hair red, but left Denning’s blond locks alone. It’s been so long ago I don’t remember why they did it that way. ‘Unknown Island’ was one of the fun ones.

I am a Mormon. Dad was and I was raised in that religion and during the '30s and '40s, I strayed and got into others things. I drank, I smoked, and did things totally opposite, not even thinking of what I had known during childhood. I remember in 1958, two elders came to my door and I began to think about my upbringing and what I learned and than I started to meditate on that and I found solace once again and realized what I had been neglecting, if not forgetting, all those years when I was out of circulation. I returned to my Mormon roots around Christmastime that year and became very active in the church again. I'm glad those young man dropped in and reminded me about what I'd been missing because if not I would've missed out on what the true "big picture" is. (Note the quote about being a Mormon is not sourced and is disputed: “Deleted quote about Virginia Grey being a member of the LDS church. I am her biographer and have spoken to members of her immediate family. They don't know why that quote was attributed to her. She was a lifelong devout Catholic.” See, main article history.)
