Frankfurt, Aug 06: German star - lookalikes have gathered in Frankfurt. Marilyn Monroe, Sylvester Stallone, and the German pop star Nena, among others, all gathered in Frankfurt on Monday for a sing-along... but after closer inspection, it was a group of lookalikes masquerading as the real thing. About 20 lookalikes, ranging from famous tenor Luciano Pavarotti to Laurel and Hardy to Terminator-star Arnold Schwarzenegger, met to advertise their craft, and try to draw more people to shows featuring the imitators.
