Shahab Hosseini (The Salesman) is set to star as Iranian-American physicist and inventor Ali Javan in an upcoming biopic to be written and directed by Kourosh Ahari (The Night). Javan first proposed the concept of the gas laser in 1959 at the Bell Telephone Laboratories. A successful prototype, constructed by him in collaboration with W. R. Bennett, Jr. and D. R. Herriott, was demonstrated in 1960.
