Martinelli moved to Rome with her family and in 1953 was discovered by Roberto Capucci who introduced her to the world of fashion. She became a model and began playing small roles in films. She appeared in Claude Autant-Lara's Le Rouge et le noir (1954), but her first important film role came the following year with The Indian Fighter opposite Kirk Douglas.
