Mel Gibson is a happy man this week. Tired to the point of exhaustion, as he sucks a cigarette down to its filter in a Los Angeles hotel suite, but undeniably happy. Opening last Wednesday, his new film, The Patriot, grabbed the number one spot at the box office on the eve of its US premiere. Notably, it came at the expense of another movie, Chicken Run, the Aardman animated feature in which Gibson also happens to lend his voice to a rebellious rooster named Rocky.
