Question: Was the TV series in which Colin Tapley costarred with Donald Gray still on the air during World War II? Passage:In 1933, film company Paramount Pictures wanted to re-juvenate and diversify its contract players, and launched a competition known as the "Search for Beauty"; heats took place in nations across the English-speaking world. Elred Tidbury entered in his native South Africa and was selected with Lucille du Toit, a dental nurse from Pretoria, as one of the winners. Colin Tapley, who would later appear opposite Gray in the TV series Mark Saber, was the New Zealand male winner. In total, there were 30 finalists worldwide, who were screen-tested over six weeks at the end of 1933. Of the 30, bit player contracts were awarded to 10, and Tidbury was selected as the overall male winner with a bonus of US$1,000, with which he bought a car. The overall female winner was Scottish actress Gwenllian Gill, who later followed Tidbury to Britain and became engaged to him; however, their engagement was broken off during the Second World War.
