Vials of blood, dungeons and razorblades! Billy Bob Thornton's relationship with Angelina Jolie sounded pretty out there at the time.

Now, the "Fargo" actor is setting the record straight about his "whirlwind" relationship with Jolie, although he does admit that time of his life was "pretty crazy."

Talking with The Hollywood Reporter, Thornton, 59, explained the "vials of blood" that he and Brad Pitt's current wife became notorious for during the early 2000s, weren't all that they seemed.

"I mean it was a crazy time. I've never been fond of it," the actor explained. "[The] vial of blood is very simple. You know those lockets you buy that are clear and you put a picture of your grannie in and wear it around your neck? She bought two of those," he told the outlet.

"We were apart a lot because she's off making 'Tomb Raider' and I'm making 'Monster’s Ball.' She thought it would be interesting and romantic if we took a little razorblade and sliced our fingers, smeared a little blood on these lockets and you wear it around your neck just like you wear your son or daughter’s baby hair in one. Same thing. From that, we were wearing quart jars of blood around our necks. And we were vampires and we lived in a dungeon."

The award-winning actress and activist is one half of one of Hollywood’s most powerful couples.

There was, in fact, no dungeon, Thornton insists. Reports suggesting there were, were the result of selective hearing.

"I mean, it had some basis in fact. We had a basement which I had a recording studio in. So when I tell a journalist I stay down in the dungeon all the time, you know, recording music, they don’t hear 'recording music,' they hear 'dungeon,'" he explained. "You know, because it makes a better story."

Jolie and Thornton were married for three years between 2000 and 2003. In 2012 the actor told ABC's "Nightline" he still had a lot of affection for Jolie.

"We had a great time together," he said. "We had a great marriage and I chickened out because I didn't feel good enough. That's all that happened. It was no big deal, we never hated each other."
