Mookilla Rajyathu is a Malayalam movie released in 1991 directed by the duo Ashokan-Thaha featuring Mukesh, Siddique, Thilakan and Jagathy in the lead roles. This comedy flick revolves around four patients who escape a mental asylum, their antics and the mischief they get up to while trying to start life in a "normal" society, which, as the title appears to insinuate, often fares worse in terms of sanity. The movie is a derivative of the successful comedy film The Dream Team, 1989.The film starts by displaying an antic of Keshavan (Thilakan) who is an inmate of the Kakkanad Mental Hospital. Two other inmates are Benny (Mukesh) and Krishnankutty (Jagathy Sreekumar), along with the female inmate played by Philomena. The late Hakeem Rawther too plays as an inmate in a cameo role. By profession Benny is an artist, Krishnankutty is an auto-mechanic and Keshavan had retired from military service. The trio chance to come across a newspaper report that the Hindi film star Amitabh Bachchan is visiting Ernakulam City for film shooting, which is near the place they stay. They are soon joined by Venu (Siddique), acting as the brother of Balan (N. L. Balakrishnan) who takes him to the mental hospital. Venu is a good singer but suffers from a compulsive obsession to singing.
