Rob Lowe was stunned to find Seth Rogen wandering around an airport alone at the height of the cyber terrorist attack on his comedy The Interview.

Lowe, who appears in the film, was shocked when the movie sparked an international incident between North Korea and America last month (Dec14), prompting Sony bosses to initially pull the project from a planned Christmas Day (25Dec14) release.

But the Wayne's World star was even more amazed when he bumped into a carefree Rogen at an airport over the holidays.

He says, "I'm going to Jfk (Airport in New York) and I'm in the check-out line... and there's Seth Rogen. I'm like, 'Wait a minute, there's no security...' He's just, like, right there... He was like, 'What gate am I at?'

"I'm like, 'There are people trying to actively murder you'."

In the film, Rogen and James Franco play hapless Tv journalists assigned to assassinate North Korean leader Kim Jong-Un.

Lowe, who has an uncredited role in the comedy, insists he never thought he was at risk from the cyber terrorists.

He adds, "I figured the North Koreans were like, 'Oh no, Rob Lowe, he's funny in it; he's fine'."
