KILL-CRAZED PERSON OF INTEREST: NO KISSING ALLOWED!

JIM CAVIEZEL of the hit series “Person of Interest” would rather kill than kiss on-screen!

That’s because the 43-year-old actor, who played Jesus in “The Passion of the Christ,” is a de­vout Roman Catholic and says a screen smooch would feel like he was being unfaithful to his wife, former teacher Kerri.

“Jim doesn’t like to kiss an actress unless it’s just a little peck – and even then it’s got to be with his character’s wife or girlfriend,” divulged a CBS insider. “He’s a very moral man and doesn’t want to send the wrong message when it comes to intimacy.”

In the CBS series, Jim plays John Reese, a former member of the elite Special Forces who sometimes metes out vigilante-style justice to take down bad guys – even killing them when neces­sary.

To prepare for the role, Jim spent a lot of time with real-life Special Forces operatives and weapons, including rifles and sub-machine guns that he learned to break down blindfolded.

Although Jim doesn’t mind killing on-screen, loving is a big NO-NO.

In 2001, he refused to do a nude scene with Jennifer Lopez in the thriller “Angel Eyes” out of “devotion, love and respect to my wife.” And while film­ing “High Crimes” in 2002, he nixed doing nude scenes with his on-screen wife Ashley Judd.

“Jim doesn’t care what other people think about his own per­sonal code of conduct, on or off-screen,” noted the insider.

“He only worries about what he does in the sight of God...AND his wife!”
