LOS ANGELES (AP) ? In yet another example of network skittishness in the wake of Janet Jackson?s Super Bowl flashing, PBS says it will alter a movie scene to avoid showing the front of a nude woman being scrubbed down after a fictional chemical attack.

Extra footage in the movie ?Dirty War? will be used that depicts the woman from a more discreet angle, PBS senior programming executive Jacoba Atlas said on Saturday.

It is one of three HBO-produced films that will be seen on PBS stations in coming months after they are shown on the pay cable outlet.

?Dirty War,? about a terrorist ?dirty bomb? attack on London, will include the nude scene when it is shown on HBO starting January 24. PBS stations will air the movie February 23.

At a time when the Federal Communications Commission is aggressively pursuing indecency complaints, a nonessential nude scene in a fictional movie isn?t worth the risk, Atlas said.

The FCC last fall fined CBS $550,000 for Jackson?s notorious wardrobe malfunction, making many networks and broadcasters nervous about airing nudity, violence or bad language.

Not only would the always financially strapped PBS put itself at risk, but the scene could deter many of the system?s 170 individual stations from airing an important film, Atlas said. ?You want to pick your battles,? she said.
