Novels like Gladiator (said to be an inspiration for Superman) and The Savage Gentleman (said to be an inspiration for Doc Savage) also were noticed. Wylie's non-fiction screed Generation of Vipers (1942) also attracted a lot of attention. They were very popular, and a movie was made in 1951, produced by George Pal (and departing quite a lot from the plot of the novels). His two collaborations with Edwin Balmer, When Worlds Collide (1933) and After Worlds Collide (1934), concern a rogue planet colliding with Earth, and an escape to the planet's moon. His most famous novel may be The Disappearance (1951), in which the world splits into two timelines, one with all the men, the other with all the women. Much of his work was SF, though he did not work within the confines of the genre. Philip Wylie was once a very famous writer, both for his polemics and his fiction.
