14. Marilyn Monroe and Tony Curtis
Monroe and Curtis were well-known lovers before they began filming Some Like It Hot. However, Curtis had a completely different opinion of Monroe throughout filming. He began to grow tired of how late she would appear on set and he once he even said that kissing Monroe was “like kissing Hitler.” A few years after her tragic death, Curtis was quoted reminiscing about her behavior around that time, stating, “She’d gone funny … her mind was all over the place.”
