Johnny Depp stars in the film as an ancient vampire who wakes from a long sleep to reconnect with his descendants in the 1970s.
In a recent interview, Burton revealed that he enjoyed exploring a bizarre family "dynamic" in the dark comedy.
"Families are just such a strange thing. I mean, for me it doesn't matter if people are rich or poor, whatever nationality, all families have a strange dysfunctional thing to them… good families, bad families, there's always a twisted element to them," Burton said, reports Flicks and Bits.
He added: "One of the reasons I wanted to do this [is that] it explores the weird natures of what families are - any family. I always thought my friends' families were much better than mine, then you kind of dig into the surface and it's like they're all weird."
Burton also insisted that his frequent collaborator Depp was the perfect choice to play Barnabas.
"I could see right away that Johnny had a passion for Dark Shadows when he came to me, and he really wanted to do it - we'd been talking about doing it for a couple of years, several years," he said.
"So I knew it was something that was stewing inside of him for a long period of time. And he always puts 100% into his characters, so I was really excited what this one would be, Barnabas Collins, in this absurd time, with this family."
Dark Shadows opens on May 11 in US and UK cinemas.
