Speaking in a new behind-the-scenes video for the soap's official website, the film actor reflected on his decision to join EastEnders and hinted at what lies ahead for Derek.
Foreman explained: "Derek Branning is going to be one of those characters that's going to really set things alight in the Square. When I was asked to play the part, they told me that he was dangerous, destructive and sexy. Well, I haven't seen much of the sexy, but I've seen lots of the dangerous and lots of the destructive!
"So I think you're going to enjoy him. I think he's one of those characters you're going to love to hate. You never know what he's going to do next. And I'm just waiting for little old ladies to come and beat me with their handbags!"
He continued: "I have been asked to appear in the show a couple of times before, and it never seemed quite the right time for me. But [then] this character came up - Derek Branning, the oldest Branning brother, back out of prison after all these years coming back to cause havoc in the Square.
"To be with the family and to be with the actors that I'm so lucky to work with every day was just an offer I couldn't refuse."
EastEnders continues tonight at 7.30pm on BBC One.
