15. The Big Cube (1964) Lana Turner
Use of Mind control -
Adriana Roman (LANA Turner), a successful stage actress, retires to marry Charles, a wealthy tycoon. Winthrop's daughter, Lisa (Karin Mossberg), is instantly distrustful of Adriana solely because she is "the other woman" taking her father's affection.
Charles is killed in a boating accident, which also leads to Adriana suffering from a concussion. Lisa's new boyfriend Johnny Allen (George Chakiris), a womanizing, fortune-hunting medical student, capitalizes on that distrust to persuade Lisa that her father's death was murder, a charge exacerbated by Adriana's threat—as per her late husband's instructions as laid out in his will, for which Adriana is executor—to disinherit Lisa if she marries Johnny.
Johnny conspires with Lisa to lace Adriana's prescribed sedatives with enough LSD to drive her insane. In addition, while Adriana is having LSD-induced hallucinations, they plan on playing pre-recorded subliminal messages to further drive her crazy.
