In this video report from CNN, documentary film director Malik Bendjelloul talks about how he used a $1.99 iPhone app to finish shooting his Oscar-nominated film, “Searching for Sugar Man.” The film tracks the rise to fame of the Detroit musician Rodriguez, who never made it big in the United States but became a legend in South Africa. Bendjelloul started shooting the movie on film, but with just a few shots remaining, he found his budget depleted. That’s when he turned to an iPhone app called 8mm by Nexvio, which gave his video a retro feel. “It looks like real film,” says Bendjelloul. “You can’t tell the difference.” “Searching for Sugar Man” has garnered praise at the Tribeca film festival, SXSW Film, and the Los Angeles Film Festival.
