Input: Consider Input: 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.

The division took Fort du Roule after a heavy engagement and entered Cherbourg, 25 June. It was around this time that Corporal John D. Kelly and First Lieutenant Carlos C. Ogden, both of the 314th Infantry Regiment, were awarded the Medal of Honor. It held a defensive line at the Ollonde River until 2 July 1944 and then returned to the offensive, taking La Haye du Puits in house-to-house fighting, 8 July. On 26 July, the 79th attacked across the Ay River, took Lessay, crossed the Sarthe River and entered Le Mans, 8 August, meeting only light resistance. The advance continued across the Seine, 19 August. Heavy German counterattacks were repelled, 22–27 August, and the division reached the Therain River, 31 August. Moving swiftly to the Franco-Belgian frontier near St. Amand (east of Lille), the division was then moved to XV Corps in eastern France, where it encountered heavy resistance in taking Charmes in street fighting, 12 September. The 79th cut across the Moselle and Meurthe Rivers, 13–23 September, cleared the Forêt de Parroy in a severe engagement, 28 September–9 October, and attacked to gain high ground east of Emberménil, 14–23 October, when it was relieved, 24 October.
