Apart from its strong and innovative film tradition, France has also been a gathering spot for artists from across Europe and the world. For this reason, French cinema is sometimes intertwined with the cinema of foreign nations. Directors from nations such as Poland (Roman Polanski, Krzysztof Kieślowski, Andrzej Żuławski), Argentina (Gaspar Noé, Edgardo Cozarinsky), Russia (Alexandre Alexeieff, Anatole Litvak), Austria (Michael Haneke) and Georgia (Géla Babluani, Otar Iosseliani) are prominent in the ranks of French cinema. Conversely, French directors have had prolific and influential careers in other countries, such as Luc Besson, Jacques Tourneur or Francis Veber in the United States.
