In interviews during production, Tate expressed an affinity for her character, Jennifer North, an aspiring actress admired only for her body. Some magazines commented that Tate was viewed similarly and "Look" published an unfavorable article about the three lead actresses, describing Tate as "a hopelessly stupid and vain starlet". Tate, Duke, and Parkins developed a close friendship that continued after the completion of the film. During the shooting of "Valley of the Dolls", Tate confided to Parkins that she was "madly in love" with Polanski. "Yes, there's no doubt that Roman is the man in my life," Tate was quoted as saying in the New York "Sunday News". Tate promoted the film enthusiastically. She frequently commented on her admiration for Lee Grant, with whom she had played several dramatic scenes. Tate was quoted as saying, "I learned a great deal about acting in ["Valley of the Dolls"], particularly in my scenes with Lee Grant... She knows what acting is all about and everything she does, from little mannerisms to delivering her lines, is pure professionalism."
