Viktor Suvorov
The Prague Spring is featured in several works of literature. Milan Kundera set his novel "The Unbearable Lightness of Being" during the Prague Spring. It follows the repercussions of increased Soviet presence and the dictatorial police control of the population. A film version was released in 1988. "The Liberators", by Viktor Suvorov, is an eyewitness description of the 1968 invasion of Czechoslovakia, from the point of view of a Soviet tank commander. "Rock 'n' Roll", a play by award-winning Czech-born English playwright Tom Stoppard, references the Prague Spring, as well as the 1989 Velvet Revolution. Heda Margolius Kovály also ends her memoir "Under a Cruel Star" with a first hand account of the Prague Spring and the subsequent invasion, and her reflections upon these events.
