London, Jan 25 (ANI): Hollywood actor Mel Gibson says all men are "dogs".

The 53-year-old Braveheart star is stepping into the shoes of a father who seeks revenge for his daughter's murder in his upcoming flick Edge Of Darkness.

And Gibson has now become very protective of his own three-month-old daughter Lucia by lover Oksana Grigorieva, 39.
