LONDON — Whoops of raucous applause greeted the world premiere of Working Title’s comedy “Sixty Six” which took place Oct. 23 at London’s Empire, Leicester Square.

The pic about an under-confident 13-year-old Jewish boy who becomes obsessed with the meticulous planning of his own bar mitzvah, only for it to be upstaged by England’s unlikely advancement to the 1966 soccer World Cup final, went down a treat with Brit auds.

Helmer Paul Weiland revealed his own big day had been blown out of the water by the ’66 Cup: “23 people arrived for my bar mitzvah, 12 left early, leaving plenty left over from the buffet for 150. … I’m just pleased I can celebrate my bar mitzvah here 40 years later with 1,500 people!”

Working Title’s Tim Bevan introduced the comedy, which he produced with WT partner Eric Fellner and Elizabeth Karlsen.
