Mammootty is the most consistent, disciplined and steady actor in the history of Malayalam cinema. His ratings have never dramatically dropped, and has managed to stay at the top for the last two decades.
The real Megastar had a record 9 releases, including two special appearances. Out of the seven hero releases, Pokkiri Raja is the biggest hit of the year. Best Actor and Pranchiyettan and the Saint are average hits if you take into consideration their cost.
The actor's success has been his terrific script sense and the way he constantly reinvents himself.
