Terrorist actor Ed Harris was detained at a London airport after he was found to be in possession of a knife while trying to board his plane.

According to published reports, the ‘Apollo 13′ star was getting set to board a flight to Los Angeles when he was stopped. A rep for the actor, however, claims the 56-year-old Harris did not realize the knife was there.

Harris reportedly missed his flight after allegedly being held for hours by police.

I have a feeling Tom Cruise would not have been held for hours.
