Igor and Grichka Bogdanov, Double Trouble
Seeing not just one but two similar-looking attractive guys will surely get anyone’s attention, which explains why French twins Igor and Grichka Bogdanov easily rose to fame. The duo was famous during the ‘70s for presenting various subjects in science fiction, popular science, and cosmology. However, their names made even more waves as they were involved in what is known as the Bogdanov affair, which claims that the brothers wrote nonsensical advanced physics papers and were published in reputable scientific journals.
