The 1960s and 1970s saw a greater variety of artistic styles in Soviet cinema. The comedies of Eldar Ryazanov and Leonid Gaidai of that time were immensely popular, with many of the catchphrases still in use today. In 1961–68 Sergey Bondarchuk directed an Oscar-winning film adaptation of Leo Tolstoy's epic ''War and Peace'', which was the most expensive film made in the Soviet Union. In 1969, Vladimir Motyl's ''White Sun of the Desert'' was released, a very popular film in a genre of ostern; the film is traditionally watched by cosmonauts before any trip into space. In 2002, ''Russian Ark'' became the first feature film ever to be shot in a single take. After the dissolution of the Soviet Union, the Russian cinema industry suffered large losses—however, since the late 2000s, it has seen growth once again, and continues to expand.
