Why did Zayn Malik quit 1D? 'This is Us' director reveals his 'struggle'

Filmmaker Morgan Spurlock, the director of the One Direction documentary "This Is Us," says Zayn Malik "struggled the most" with tour demands. Speaking to HuffPost Live on Tuesday, Spurlock revealed that he always knew ex-member Malik found fame hard to deal with. Zayn Malik confirmed he'd quit the band last week, announcing in a statement on March 25 that he wanted to live like a "normal" 22-year-old. One Direction have vowed to continue as a four-member band.
