In 1955, soon after she arrived in Hollywood, her agent wanted to get her an interview with
Cecil B. DeMille. He took her to lunch on the
Paramount lot, and the great director noticed her. She resembled the drawing he had made of "Sephorah", the wife of "Moses", in
The Ten Commandments (1956). DeMille asked her to come to his office. There, under orders from her agent, she didn't mention that she was under contract to Universal-International. DeMille had her working on a scene with
Henry Wilcoxon. When DeMille was informed that Allison was a U-I employee, he threw her and her agent off the lot.
