It’s Sean Penn as we’ve never quite seem him before, as a fading, androgynous rock star who sounds oddly like Droopy the Dog. In the intriguing This Must Be The Place, Penn plays Cheyenne, a wealthy former rock star, now bored and jaded in his retirement, who embarks on a quest to find his father’s persecutor, an ex-Nazi war criminal now hiding out in the US. Learning his father is close to death, he travels to New York in the hope of being reconciled with him during his final hours, only to arrive too late. Having been estranged for over 30 years, it is only now in death that he learns the true extent of his father’s humiliation in Auschwitz at the hands of former SS Officer Aloise Muller – an event he is determined to avenge. So begins a life-altering journey across the heartland of America to track down and confront his father’s nemesis.Penn’s characters certainly makes an unlikely avenger.
