Also in 1982, Seth played Indian author Victor Mehta in David Hare's biographical play, A Map of the World, which toured for several years in Australia, London, and New York. After the release of the multi-award-winning movie Gandhi (1982), Seth was much in demand, and when A Map of the World's Broadway run finished, his movie career took off. His work in 1984 included major roles in Indiana Jones and the Temple of Doom and David Lean's A Passage to India. Following that he played a lead in My Beautiful Laundrette (1985), and he played Pancks in Little Dorrit (1988).
