She quickly became one of the most popular musical comedy stars in Europe. Lillian was offered a contract with Hal Roach in 1934 and came to America. Roach said he wanted to make her into the next Thelma Todd. Her press agent described her as "a slim exquisite beauty of the continental type with eyes of cerulean blue and golden blonde tresses."
