I absolutely would be up for that. It could be very, very amazing, Somerhalder said. I have the book and I just started reading it. That would be a pretty incredible thing, and hopefully that could pan out.

Adding, Beyond the shadow of a doubt, I think that would be a phenomenal opportunity!

Ian Somerhalder's popularity has skyrocketed with the success of his CW show, in which he stars with his on-screen and off-screen girlfriend, Nina Dobrev.

Somerhalder has also had roles in Lost, Smallville and the 2000 series Young Americans, as well as movies like The Tournament and Cradlewood.
