 Due to financial crises , it took more than one and a half years for Gopalakrishnan to finish the film . Swayamvaram was one of the first Malayalam films to use synchronised sound and to be filmed in outdoor locales , for which Gopalakrishnan used his Nagra audio recorder . The film was shot in two schedules . It was delayed due to scheduling conflicts of the lead actress , Sharada . She was working in several films at that time , so Gopalakrishnan had to arrange the schedule to suit her convenience . The lead actor , Madhu , mentioned in an interview that Gopalakrishnan was clear about his characters and their behaviour . Gopalakrishnan also used to discuss the shoot with his crew before the shooting .
