Mammootty has also appeared in Tamil, Telugu, Kannada, Hindi and English-language productions. In a career spanning five decades, Mammootty has acted in over 400 films.

Mammootty made his debut in acting through Malayalam film Anubhavangal Paalichakal in 1971. His first leading role was in I. V. Sasi's unreleased film Devalokam (1979). Mammootty's breakthrough came in 1981 when Mammootty received the Kerala State Film Award for Second Best Actor for his performance in Ahimsa. Major commercial successes during this time included the 1983 films Sandhyakku Virinja Poovu and Aa Raathri. Following a series of box office failures, the 1987 crime thriller New Delhi improved his commercial prospects. The films that followed through the next decade established Mammootty as one of the leading stars of Malayalam cinema.

The 2000s were a period of critical and commercial success for Mammootty. His performance in the Hindi and English-language bilingual biopic Dr. Babasaheb Ambedkar (2000) won him the National Film Award for Best Actor, and Mammootty won Kerala State Film Awards for Kaazcha (2004) and Paleri Manikyam (2009).
