Liam Neeson is a protective kind of guy, but watch what happens after actress Maggie Grace, his co star in “Taken,” told him about a boyfriend not treating her properly.

She recounted the tale on the Conan O’Brien show and it is truly remarkable.

Liam decides to take the situation into his own hands, or rather those of his character Brian Mills.

The restaurant phone call is as funny as it gets as Liam warns the ex about his behavior and threatens all kinds of physical violence.

In real life, Grace says, Liam was the perfect screen dad and, that they have played opposite each other in "Taken" films for almost nine years and she loves the guy.

But the ex-boyfriend should be afraid, Very Afraid.
