Question: Shock Treatment is a follow up to the film by which studio?
Context: Electroconvulsive therapy (ECT), formerly known as electroshock therapy, and often referred to as shock treatment, is a psychiatric treatment in which seizures are electrically induced in patients to provide relief from mental disorders.  The ECT procedure was first conducted in 1938 and is the only currently used form of shock therapy in psychiatry.  ECT is often used with informed consent as a last line of intervention for major depressive disorder, mania, and catatonia.  ECT machines have been placed in the Class III category (high risk) by the United States Food and Drug Administration (FDA) since 1976. Shock Treatment is a 1964 American neo noir drama film directed by Denis Sanders that takes place in a mental institution, starring Stuart Whitman, Carol Lynley, Roddy McDowall and Lauren Bacall.

The album went to No. 13 on the "Billboard" Pop Albums chart, and had two charting singles: "Easy Street" (#83 Pop Singles) and "River's Risin'" (#33 Pop Singles). The Rocky Horror Picture Show is a 1975 British-American musical screwball comedy horror film by 20th Century Fox produced by Lou Adler and Michael White and directed by Jim Sharman.  The screenplay was written by Sharman and actor Richard O'Brien, who appears in the film, which is based on the 1973 musical stage production "of the same title", with music, book, and lyrics by O'Brien.  The production is a parody tribute to the science fiction and horror B movies of the 1930s through to the early 1970s.  Along with O'Brien, the film stars Tim Curry, Susan Sarandon, and Barry Bostwick and is narrated by Charles Gray with cast members from the original Royal Court Theatre, Roxy Theatre, and Belasco Theatre productions. Shock Treatment is the third studio album by American rapper Krizz Kaliko, released on September 14, 2010.

Shock Treatment (French: "Traitement de choc" ) is a 1973 French drama film directed by Alain Jessua.  It was released in the UK by distributor Antony Balch as "Doctor in the Nude". Dronedarone (development codename SR33589 and marketed as Multaq) is a drug by Sanofi-Aventis, mainly for the indication of cardiac arrhythmias.  It was approved by the FDA on July 2, 2009.  It was recommended as an alternative to amiodarone for the treatment of atrial fibrillation and atrial flutter in people whose hearts have either returned to normal rhythm or who undergo drug therapy or electric shock treatment i.e. direct current cardioversion (DCCV) to maintain normal rhythm.  It is a class III antiarrhythmic drug.  In the United States, the FDA approved label includes a claim for reducing hospitalization, but not for reducing mortality, as a reduction in mortality was not demonstrated in the clinical development program.  A trial of the drug in heart failure was stopped as an interim analysis showed a possible increase in heart failure deaths, in patients with moderate to severe CHF. Shock Treatment is a 1981 American black comedy musical film directed by Jim Sharman, and co-written by Sharman and Richard O'Brien.  It is a follow-up to the 1975 film "The Rocky Horror Picture Show".
