Playing the titular character in a TV adaptation of a popular book series can present many challenges. Actor Ramón Rodríguez, who stars as Will Trent in the ABC drama, told us that the cast and crew really tried "to honor these characters," but admitted that the TV series has a different format compared to the books.

"For instance, in some of Karen's books, it'll be one case for the whole book. We're not going to be doing that on this show," he told us. "We'll be mixing some cases."

The actor told us that he hopes the TV series ultimately honors Karin's work, and also wants people who aren't aware or haven't read the books to feel "really intrigued and excited by [the story]."

Will Trent will premiere on Tuesday, Jan. 3, at 10 p.m. EST on ABC.
