When the going gets tough, the tough get going

This means, that when it gets tough, really tough, you shall know that a man who has courage will not stop, instead will get till the end, completely involved, pulling out the best of his character. This expression comes from the American movie “Animal House” (1978), directed by John Landis, having as protagonist the brilliant John Belushi. Bluto, the protagonist, gets involved in the most grotesque situations, in a fiercely and determined research for most unrestrained fun (the tough play, so to speak). The film has become a cult and had an impact not only on the American cinematography but also influenced the lifestyle of a young American generation.
