Padumatthera Som, known also as Som, one of the best writers in the Khmer language. Some talented members of Khmer royalty such as King Ang Duong (1841–1860) and King Thommaracha II (1629–1634) have produced lasting works of literature as well. King Thomaracha wrote a highly esteemed poem for younger Cambodians. The prolific King Ang Duong is most famous for his novel Kakey, inspired from a Jataka tale about an unfaithful woman. While not written as a work of instruction, Kakey is often used as an example to teach young Khmer girls about the importance of fidelity.

Many films were being screened in theaters throughout the country by the 1960s, which are regarded as the "golden age". After a decline during the Khmer Rouge regime, competition from video and television has meant that the Cambodian film industry is relatively weak today.
