The only movie based on the absurd world of Vivian Stanshall - the eccentric frontman of the Bonzo Dog Doo-Dah Band - Sir Henry At Rawlinson End is either a work of sublime genius or unmitigated crap, depending on who you speak to. In fact, Stanshall himself - who co-wrote the screenplay - was so horrified by the final cut, he tried to stab the director at a preview screening ("My wife knew what I was doing," Stanshall said, "but I was so pissed and full of pills and nerves that I fumbled getting my penknife out and she managed to arrest me in time.").
