Selleck wants lighter shade of Blue

Tom Selleck has promised Blue Bloods fans they will be getting deeper "inside" his character in the next series.

The 67-year-old plays Frank Reagan, the New York Police Department commissioner and patriarch of a family devoted to law enforcement and each other, in the hit TV show, which will be back for a third season.

Tom said of his role: "A commander can't expose his weakness or doubt or concern or worry. I have to show all those things to the audience without showing it to the cops I'm ordering around.

"When you get inside Frank's head, you realise that anybody with the weight of the world on his shoulders will exhibit flaws that come from dealing with that kind of pressure. I think next season we're going to get inside of him more and reveal more of them."

At the same time, the actor hopes the show will find some lighter moments.

"I can't sit around giving orders all day," he said. "They cast me because I can play bosses. But I have other colours I can play."
