Alekar had cut his directorial and playwriting teeth on a one-act college show, Jhultapul or 'Swinging Bridge' in 1969. After that he assisted Patel to direct Ghashiram Kotwal. His first full-length script was Miki ani memsaheb i.e. 'Miki and the Memsahib' in 1974. With the exception of Mahapur i.e. 'Great Flood' in 1975, he went on to direct all his plays. Alekar's best known work, Mahanirvan or 'Great Nirvana' in 1973, translated as The Dread Departure, one act in its first draft, was later expanded by him at Patel's insistence and ran intermittently till 1987. His most complex play, Begum Barve in 1979, considered a classic of contemporary Marathi theatre, deals with the eponymous female impersonator's memories and fantasies. A minor singer-actor cast out on the streets after his musical company closed down, he now sells incense sticks and is brutally exploited by his employer. On a magical day his fantasies get enmeshed with those of a pair of clerks, his regular customers, and are almost fulfilled. Satish Alekar's other plays comprise Shanivar-ravivar i.e. 'Saturday and Sunday, 1982 and Dusra samna i.e. 'Second Confrontation' in 1987. Both of them were conventionally structured and produced for the mainstream stage, and Atireki i.e. 'Extremist' in 1990), which marked a return to his earlier mode of irony, wit, and tangential take-offs from absurd premises. He has also written a few screenplays, and was appointed director of the Lalit Kala Kendra, Pune University, in 1996.
